ProjectX Sessions on Controls & Instrumentation Conveners M. Wendt, C. Briegel, W. Blokland

Contents Overview presentations – Controls: Hardware and Software – Instrumentation: Collaborations and R&D Summary -Focus on collaboration and R&D

Controls Hardware HRM: Hotlink rack monitor (Paul Kasley) A general I/O box which can provide collaborators an easy connection for monitoring analog and digital data. Xclock: Synchronization (Charlie Briegel) TClock is being redesigned as XClock. These clocks provide the complex with global synchronization of all machines and related data acquisition. TClock/XClock is not a machine clock. A machine clock for project X needs to be addressed.

Controls Hardware Bus Survey aka Hardware Platform (Charlie Briegel) Many options are being investigated. The VME hybrid (VXS, openVPX) provides a growth path for future platforms. While Project X implementations are not dependent on a particular architecture, efficiency can be achieved by minimizing the choices across the complex. The choice of future bus architectures will evolve as the industry matures.

Controls Software GUIs aka Console Environment (Carl Shumann) – JAVA applications (SYNOPTIC viewer), EDM screens, MATLAB, and the existing CLIB (including ACL) provide the tools for operators/physicists. – A modeling/simulation framework is missing. The existing redirection of data for a framework could allow virtual machines as well as real machines to be manipulated, but the physics view of the machine is not directly tied to the control system. This effort could be addressed with a collaborative effort but must involve the machine physicists. Alarms (Brian Hendricks) – Alarms hierarchical view or “processed” alarms could be a collaborative effort. A rule-based system as a client of the current set of alarms could serve an intelligent set of resulting alarms.

Controls Software EPICS to ACNET (Dennis Nicklaus) – This wrapper around an EPICS IOC has been implemented to provide allow collaborators to provide a EPICS system that can be integrated in the ACNET control system ACNET-in-a-Box (Rich Neswold) – Provides a minimal system for collaborators to evolve their system for Fermilab.

Wilcox)

Collaboration: Fast Faraday Cup Irregular spacing avoids resonance 316 Stainless Presentation_name Input pulse phase dispersion Transmission from connector to connector Transmitted pulse only a 4psec increase in risetime ( Craig Deibele)

Collaboration: Electron Scanner Electron scanner: derive the beam profile by looking at the deflected projection of a tilted sheet of electrons due to the proton beam S X Y protons electrons To get started without a fast deflection system use multiple measurements of a stepping pencil beam. S X Y protons electrons Assume scan duration << proton bunch (W. Blokland) Simulations show that scan must be shorter than bunch length to use same method as SNS.

SLAC is interested in an official PX collaboration on this subject. (Tao Tang)

Initial setup of a temporary diagnostics beam-line to characterize the beam parameters after the RFQ at HINS. Many upgrades underway, e.g. spectrometer for dp/p, Feschenko, vibrating wire, fast Faraday cup, laser emittance, etc. PX Instrumentation R&D at HINS (Vic Scarpine)

Summary (Controls) General Purpose DAQ: HRM – A custom but tightly coupled (TCLOCK) general purpose data-acquisition system is available Synchronization and Time-stamping: XCLOCK & BSYNC – The beam synchronization specifications for the IC-2, aka the BSYNC clock, need to be determined. This will require experts from instrumentation, controls, machine groups and LLRF. Hardware Platform: – Different platforms are being investigated, VME hybrid is main local choice but collaborators will be supported. The final choice(s) will (and can) be made later. Console Graphical Interface – Current tools EDM, CLIB, Java (including drop and drag interface), ACL. Discussion on what console tools will be needed by different groups such as operators, diagnostics, physics. – Consider supporting the use of an accelerator simulation model tied to the console environment to help with zero th order tune-up of accelerator (center of mass) and debugging of applications. This can be a collaboration opportunity. Alarms: dedicated program with Central Alarm Server – Identified possible collaboration opportunity for intelligent manager of alarms EPICS-ACNET: The assumption is that the underlying control system is ACNET – This layer will allow collaborators to provide EPICS-based instrumentation ACNET-in-a-box – Allows collaborators to test an ACNET front-end at their location. This tool in combination with the assistance (visits) of Fermilab people will help integration of collaborators’ systems

Summary (Instrumentation) ProjectX Collaboration On-going Activities – LBNL: Laser diagnostics Conceptual design of a mode locked laser with optical fiber distribution, improve signal to noise with a modulated synchronous detection system – SNS: Electron Scanner Proposal to get started with available electron gun without having to build fast scanner – SNS: Fast Faraday Cup Delivered low power prototype (20Ghz) and started design of high power version Instrumentation Collaboration opportunities – FRIB: Job opportunities. Possible collaboration on similar diagnostics. Already started design on MPS – ESS: Job opportunities. Possible collaboration on similar diagnostics PX Test facility (formerly known as HINS) – Front-end serves as instrumentation and chopper test facility. Important for R&D Chopper Driver – Collaboration opportunity with SLAC Thanks to all participants
