Outline Intro Cryostat Infrastructures Detector installation Cryogenic systems Summary 2Apr 2, 2015Single Phase test at CERN

Intro The goal of this prototype is to do a test of a full scale single phase detector composed by flat panels called TPCs that hang from the roof. Each panel is about 2.5 m wide, 6.3 m tall and 0.16 m thick and weights about 600 kg. The general idea is to build a flexible facility that can potentially host other detectors in the future (including 6.9 m tall one, with same other dimensions). Similar in dimensions to the WA105 cryostat, but not identical. Current external dimensions: 10,082 mm (Transv) x 12,322 mm (Parallel) x 11,291 m (Height). The goal is to be able to run the detector before the long shut-down (mid 2018). These slides present the infrastructure requirements (as currently known) for the cryostat and cryogenic systems. 3Apr 2, 2015Single Phase test at CERN

Current assumptions Dimensions from EHN1 drawing: – Hook height above floor of pit B: 18,900 mm. – Hook clearance over top cap: 7,609 mm. Dimensions from detector design: – Detector height: 6,289 mm. – Clearance for detector installation (between height of detector and hook over cryostat): 1,320 mm. How much of this is needed for rigging and handling? Beam direction from interaction between Cheng-Ju and Ilias. 4Single Phase test at CERNApr 2, 2015

Top plate Metal plate reinforced with profiles/beams anchored to the membrane cryostat support structure with several penetrations of different size including two removable hatches and a manhole. Current dimensions: 10,082 mm x 12,322 mm x 1,500 mm (thick). Large hatch: 3,550 mm x 2,000 mm (in the current model). Small hatch: 2,000 mm x 1,000 mm (in the current model). Weight of top plate: > 25 ton Need appropriate lifting device(s) for positioning the top and the different parts that constitute it. The design is connected to the installation procedure and has to allow for different detector configurations. 11Single Phase test at CERNApr 2, 2015

Detector Installation

Detector Installation Plan(s) Currently there are two concepts on how the detector could be installed: 1)Install the detector panels by passing TPC components through a large hatch in the top cap of the cryostat. (See backup slides for some older conceptual slides). 2)The second is to build the detector directly in the cryostat without the top cap using temporary supports. Once complete, attach to the underside of the top cap. Then lower the complete assembly. (See backup slides for some older conceptual slides). Potential problems with cryogenic installation. How does the beam window(s) influence installation? Are there space limitations in the building? Personnel access: need two paths. When is the cryogenic piping installed? This will influence the amount of installation space available. Single Phase test at CERN15Apr 2, 2015

Size depends on installation technique. Crane coverageOver the cryostat and the lay down space Crane capacity for TPC (Not including the top of the cryostat) 5 ton (needs feedback from the design of the top plate). Could be the current overhead crane, but how can we integrate it inside the Clean Room ?? Could use a floor mounted gantry ?? Minimum hook height above the cryostat for TPC installation4.5 m + lifting fixture (TPCs are rotated prior to insertion) Lighting UV filtered lights are needed in all work areas where the photon detectors are exposed. Ventilation Appropriate additional ventilation when working inside the cryostat. ScaffoldingUp to 7.0m in height inside the cryostat. Power outlets For portable tools and welding machines inside the cryostat Cryostat Infrastructures Requirements 17Apr 2, 2015Single Phase test at CERN Note: some of the requirements need input from the design of the top plate, the outer structure and the beam window. They also need to be integrated with the installation process.

Current electrical requirements (Preliminary) The cryostat membrane and any supporting structure need to be isolated from any building metal or building rebar with a DC impedance greater than 300 kOhm. The cryostat, or “detector” ground, shall be separated from the “building” ground. A safety ground network consisting of saturated inductors to be used between detector ground and building ground. Single Phase test at CERN18Apr 2, 2015

Electronics and Computing Electronics Racks on top of the cryostat: safety, cooling, smoke detection, rack protection and their proximity to the detector and feedthroughs. Racks for computers. Info on Cables/Racks is being collected and will be submitted by end of April as requested in Feb by Guillaume Gros. Clean power with separate grounding for detector. How much ?? Normal power for all the rest. How much ?? Control room space for DAQ and detector monitoring. Single Phase test at CERN19Apr 2, 2015

External Cosmic Counters Need to determine if/how much coverage is needed and on what sides. There would required mechanical supports on the outside of the support structure. Access space to install and instrument will be needed around the perimeter of the cryostat. Rack space will be needed along with cable trays from the counters to the racks.

Cryogenic Systems Requirements (Preliminary) To the extend possible, we want to design a portable system that could be fabricated and tested in one place and installed at destination in another, with quick connections to/from cryostat. External Cryogenics  can be located anywhere, will probably be outside of the building. Internal Cryogenics  inside the cryostat. Proximity Cryogenics  several locations: – Condenser (and maybe LN2 dewar/phase separator) will have to be located above the roof of the cryostat or nearby, but higher than the roof of the cryostat. – LAr circulation pump at the back of the cryostat, on the floor, as low as possible. – Penetrations through the top of the cryostat, in the back region. – GAr purge in the insulation two in and two out at a certain elevation with piping going to the rest of the system. – The remaining can be located where space permits, preferably in the vicinity of the cryostat. LAr/LN2, GAr/GN2 piping will connect Proximity/External/Internal cryogenics. The design will inform on size and specific location. Apr 2, 2015Single Phase test at CERN24

Summary External dimensions are: 11,291 mm (H) x 12,322 mm (L) x 10,082 mm (W). The cryostat is ~10 degrees rotated with respect to the beam. The goal is to be able to run the detector before the long shut- down (mid 2018). Several options are available for the installation of the detector from outside and inside. They depend on the detector configuration, the design of the top cap and beam window, and the infrastructures available in EHN1. The number of racks, amount of power, # of cables, etc. also depend on the detector configuration. More defined space/infrastructure requirements will be provided in the coming months as soon as the design proceeds. 25Single Phase test at CERNApr 2, 2015

CONCEPT 2 NEEDS UPDATING WITH NEW TPC CONFIGURATION AND CRYOSTAT 31Single Phase test at CERNApr 2, 2015

Installation hardware with CPA support rail 32 Support rail length is shorter than top cap width. This rail will be fixed and supported from the underside of the top cap later. The rail is positioned close to the edge of the cryostat for allow personnel access to the hangers from the top edge of the containment vessel. Assume the top edge of cryostat can support load and that people can work there. Single Phase test at CERNApr 2, 2015

Moving CPA over Cryostat and rotation 33 Assume that there are 2 lifting devices from the crane bridge and they can be operated at the same time to rotate the TPC planes. The planes would be lifted on edge horizontally over the cryostat. One lifting device would be lowered while the other is stationary to perform the rotation of the object. Single Phase test at CERNApr 2, 2015

Positioning and attachment of CPAs to support rail 34 Once rotated the lower cable would be disconnected from the plane and the upper connection would be used to move the plane under the support rail. The plane would be connected to the support rail by personnel working from the top of the containment vessel. The second plane would be moved in and connected to complete the 1 st CPA plane assembly. Single Phase test at CERNApr 2, 2015

Translate CPA plane assembly to opposite side of Cryostat 35 Once completed, we would translate the 1 st CPA plane assembly to the opposite side of the cryostat. This could be done with rollers on the cryostat or using the overhead crane. Single Phase test at CERNApr 2, 2015

Install APA planes and translate 36 Install the APA rail and the two APA planes in a similar method. Then translate the APA planes to opposite end of the cryostat with the other CPA plane. Single Phase test at CERNApr 2, 2015

Install the 2 nd set of CPA planes 37Single Phase test at CERNApr 2, 2015

Position the 3 TPC planes 38 After positioning the 3 planes to their final positions with respect to the cryostat walls and each other, install the end field cages. These could be supported from the APA and CPA rails. How to deploy the upper field cages? When and how to cable the APA planes? The lower field cages could stored on the floor of the cryostat and connected at this point. Single Phase test at CERNApr 2, 2015

Install Top Cap 39 Bring the top cap over the 3 TPC planes and lower to the support rails. Connect the ends of the support rails to the hangers on the underside of the top cap. The HV probes could be installed through the top cap at this point into their receptacles on the CPAs. The APA cables could be “fished” through the service feed thru for connection later. Remove the installation hardware from the ends of the support rails. Lower the top cap and the TPC down in the cryostat. Single Phase test at CERNApr 2, 2015
