VTX/FVTX east repairs/upgrades required West to remain installed ?? Need to get PHYSICS FVTX/VTX lab ready by ~ mid June Meeting Monday 6/16 to discuss shutdown task details: follow up meeting next Monday 6/23 1:00 PM

6/19/ Action Items: 1. FVTX group prioritize list of IR work based on work that needs to be done with detector “cold” and what can be done when detector is “warm”. 2. M. Wysocki: Discuss needs for IR electronics testing with Miljko and report back to VTX group. 3. R. Pisani: Estimate cost and time to add a 4th chiller and split FVTX disks from VTX StriPixel Ladders 4. E. Mannel: Estimate heat load on cold loop by FVTX disks and VTXS ladders 5. E. Mannel/R. Pisani/S. Boose: Investigate adding additional temperature/humidity sensors inside the (F)VTX enclosure. 6. Mike L./ Rob P.: Look at ways of creating an “dry” zone around the (F)VTX enclosure using a portable AC unit. End of run is scheduled for July 7, It is expected that the shield wall will remain up for at least a couple of days (until July 10). Once the wall comes down, the IR will be subject to higher levels of humidity and larger temperature variations. Work can continue on the detector after the wall comes down, but most likely will have to be at higher temperatures to avoid condensation issues. Current plan is to remove the East Detector only. De-cableing of the east half will begin sometime after July 14, but can be delayed if needed for additional IR studies by the (F)VTX group. VTX StriPixels may request west half to be removed depending on understanding of bias issue in the east half and IR studies immediately after the end of Run.

6/19/ Post-Run Studies in the IR: VTX Pixels: None VTX StriPixels: Bias studies. Requires bias current measurements varying the N2 flow and warming the detector up. Warm up studies will be last after all “cold” work by (F)VTX groups is complete in order to avoid thermal cycling of the detector. Expect the work to take or order 1 day (half day cold/half day warm). Unclear if any IR work is requested by ORNL group for readout work. M. Wysocki will discuss it with ORNL group. FVTX: FVTX group has a number of problems observed only in IR (see FVTX WIKI page). Group needs to prioritize the list based on what needs to be done “cold” and what can be done once the detector is “warm” and estimate the amount of time for the work. Physics Lab Work: General: Mike L. has requested a couple of days once the detector is in the lab to look at the detector in order to see what can be done to improve the flow of N2 and better seal against condensation. VTX Pixel: Investigate one bad ladder on east detector (B1-L11). Will concentrate on one end first. Will require access to the SPIRO Board. This requires removal of FVTX 1⁄2 cage and Bigwheel, and a couple of Pixel Bigwheels. Depending on what the problem is may require access to SPIRO board on opposite end. VTX StriPixels: Investigate one bad ladder on east detector (B3-L16). Requires access to LDTB. This requires removal of south FVTX 1⁄2 cage and south Pixel Bigwheels. Depending on outcome of IR bias studies FVTX: Number of ROC issues. Can be done with 1⁄2 cages installed or removed IR Infrastructure after East detector is removed Chillers: general repair and maintenance of the 3 chillers. Requires tech time and support for BNL HVAC group. Cooling lines: Replace Teflon tubing in the vicinity of the detector with stainless steel tubing. Look at any rerouting of stainless steel lines that were added during the run. Interlocks: Review flow interlock hardware and update/modify as needed. Provide additional interlocks and monitoring for 4th chiller if added (see next item)o The VTX StriPixel group is requesting that the FVTX and StriPixel ladders be put on separate chillers. This will require purchasing an additional chiller, running additional cooling lines to the IR and installing additional manifolds at the detector. Need to estimate cost of materials and labor required to add 3rd chiller loop. N2: Look at ways of better sealing up the enclosure to reduce the leakage of N2 and migration of humidity into the enclosure. Concern that sealing the detector too tight will impact the cooling of electronics. Right now there are significant gaps at the BigWheels in part due to the age of the foam seal. Need to also re-evaluate the N2 distribution inside the detector. There was a suggestion to look at ways of creating a low humidity air volume around the enclosure. Idea would be to put some kind of “tent” around the (F)VTX and pump dry air from an portable AC unit into the enclosed volume. Region would not have to be air tight, but provide a region of drier air around the enclosure. Mike L and Rob P. will investigate options.

6/19/2014 Current Parts Dispositions (cont’d): Sensors Sensor testing at Yonsei is proceeding well, and we should have the remaining 200+ sensors from Yonsei by the end of June. We already have almost all the sensors we need for the south MPC-EX.

6/19/ From Ray Karol: Lessons Learned: Door switches fail due to improper installation Discussion: During a Search and Secure procedure for the BNL, NSLS-II storage ring, two adjacent door switches were found in the closed position when they should have been open. By the switches remaining in the closed position, the monitoring system "thinks" the door is closed when in fact, it could be open and access could be gained to the accelerator enclosure. Note that the locks and a second set of switches remained fully active during this period and the safety of staff was maintained at all times. Investigation of the event revealed that the installation of the switches was inadequate resulting in improper strike angles and/or interferences, which ultimately caused damage to the switch bodies and the premature failure of the switches. To ensure uninterrupted protection, the door switches are installed in two independent logic chains and are also redundant within that chain (i.e., two switches per chain). Due to the specific design of the switches and the method of installation, both switches failed in one of the two chains. Protection of staff was maintained throughout the period through the second chain. Findings: -Inconsistent installation. -Varying strike angles. -Interference between the switch body and the face of the door.

6/19/ Analysis: A "5 Whys" analysis was performed to assess the cause of the failure: 1) Two PPS Switches failed simultaneously by getting jammed in the closed (made) orientation (why?) 2) Either (a) the door struck the leading edge of the limit switch-body causing the internal components to be damaged or (b) the door struck the switch lever-arm while the arm was at a near-zero strike angle with respect to the door, which caused the internal components to be damaged (why?) 3) Prior to installation, a thorough review of the mechanical elements of the PPS Door/Gate Interlock System was not conducted by an experienced mechanical engineer (why?) 4) The PPS interlock system is mostly electrical in nature. The mechanical interaction between the door/gate, limit switches and "Mag Lock" appear to be straight forward but in actuality, there are many things to consider that would normally be reviewed by a mechanical engineer. The participation of a mechanical engineer was not considered in the scope of resources required to design and implement the PPS Interlock system (why?). 5) The PPS design and installation practices have not included a review by a cross-cutting team for this system. In summary, the mechanical assessment that took place on January 20, 2014, identified two probable causes for the switch failure: inadequate clearance and improper strike angle. Recommended Actions: 1) Review the Design Review process to ensure all systems are reviewed by an appropriate team of engineers and/or technical staff. All installations should be reviewed by a mechanical engineer or other qualified person prior to placing them into operation to ensure installation meets manufacturer requirements. 2) Periodically inspect all switch installations to ensure proper clearance and strike angles are maintained.
