OLD PMT vs NEW PMT

2

Old PMTs exhibit systematic gain loss vs Integrated Luminosity, rate of loss slowing down.

New PMTs (24 installed in Feb-2012) show no signs of gain changes so far (3mo, ~6fb-1)

HCAL Operations report CMS Week June 2012 Pavel Bunin, JINR, Sudan Paramesvaran,

Recent Highlights and News-I• The PMT deliveries are now completed. Testing is going well. We had a meeting with

Hamamatsu regarding our reject tubes. We have shipped back about 20 PMT’s ( low gain, high dark current and black cover problems) to be tested by them. We will give a go ahead to Sergey Los soon for the Base Board Production.

• Working on the New HV testing system and forming a committee to evaluate the RFP responses. Bulgarian new module testing is completed as well as the CAEN system. Received a detailed Draft Report from German and Alexi. Both power supplies were tested and evaluated at CERN E-pool using professional equipment and high expertise level of pool technicians.

• The HV RFP and decision committee is now formed. Members are: Germain, Alexi, Ianos, S.Los, M.Miller, D.Winn from HF and Magnus and S. Lusin from CMS Coordination.

• HF Upgrade PM will write a charge to this committee– late this week.

• We have decided on the shield length- 54 mm (looks good !! the presentation by Ianos during HF meeting on May 14thanf got confirmation by Pawel. Mike Fountain has started with the production.

Recent Highlights and News-II Gain Sorting Proposal by Ugur is now ready. -A uniform gain distribution for one HF is outlined from the first 900 PMT sample. Other than the fringes at the edge of the sample, we can get gain uniformity within2%. -EM and HAD, and 4 Quadrant separation would work if we can deliver different HV for each group (total 24 groups). -As the operation gain is decided, we can develop sorting and HV distributions for each group. - Base Board testing on the 11 Pre-production boards are done. We see no problems and requested to start for the production. We have shipped 6 boards to CERN last week. Different testing using the QIE readout was performed at CERN. Ferhat will report. -Life-time results for the first 200C is reported even if Iowa task is to verify the gain drop specs at 3000C. We have requested more info from Hamamatsu. - New cable specs for the request of quotes are ready ( Terry Shaw) -Connectors and cables for two new dark boxes are ordered. -First 864 PMT’s (900– spares) were delivered to CERN.

Recent Highlights and News-IIIThere is an agreement for a new cable purchases– Thanks Chris Tully, Jeremy Mans and Pawel De Barbaro for this. There is also a strong support from Austin and Magnus on this.

Decision is to purchase all ROBOX inside cables and 1/8 of 5m cables FEE and connector cables to the existing FEE and start installing these and purchase the remaining by Mid-2013 that we have all cables installed during LS1. This will enable us to go to the 2 channel readout option by LS1.5 or YETS (2014-15).This means that the HF FEE design and construction will go rather fast ( att. to our Turkish and Brazilian groups)HF new front end integration will be presented by Ianos. HF Electronics Packaging as well as the agreement within HCAL that we should pursue the Winchester Cables presented by Terry Shaw.Developing our “Project Org Chart” adding Brazilian Universities and ITU, Istanbul. Alberto Santoro and Gilvan-Augusto Alves are named as Co-L2’s for Brazil in our org chart. E.Gulmez BU-Istanbul is L2 for Turkey.

HF PMT UPGRADE SORTING•This is only first 900 PMTs sorted for one HF module. The absolute gain values are defined as the ratio between cathode current and anode current. The gain values listed are for 800 V, which is the manufacturer listed operating voltage for Hamamatsu R7600 PMTs. We have measured the absolute gains at 600V, 650V, 700V, 750V, 800V, 850V, and 900V. All data is on database for further needs.

•The sorting philosophy is using low gain PMTs for EM (long fiber) and high gain PMTs for Hadronic (short fiber) sections. We also divided the HF module to 4 quandrants, and 3 rings; inner, middle, and outer, with respect to eta regions. Inner ring being the highest eta region, we chose to insert low gain PMTs to inner ring, and high gains to outer ring. The possible backups are listed under every group. Total 864 PMTs are used for distribution, and 36 PMTs are assigned as backups.

•Overall 2-3% gain variation within each group is satisfied. However at the far edges of the gain distribution the gain variation gets higher, we recommend locating these high and low gain extremes, to most inner and most outer towers (13, 14, 1).

NEW CABLE SPECS HF Signal Cables – Manufacturer Winchester Electronics• Suggested improvements (from Ianos Schmidt):– REQUIRED: Cable is stiff at the shrink tubing used to terminate the outer sheath. This could present some difficulties if too long as tightest bends are required near the ends of the cables.-- Need to determine an acceptable length.– REQUIRED or WOULD LIKE ??: Would prefer longer and knurled connector nuts so that they could be turned by hand without need of a screw driver. Over tightening of jack screws on the existing D sub connectors has been a persistent problem.‐– REQUIRED: Cable connectors should be identically keyed so that cables can be easily swapped. Very important for rapid trouble shooting and fast cable replacement if necessary. Very important.‐– WOULD LIKE: Would like grips on cable connectors to ease connecting/disconnecting.• Also noted – hoods on cable connectors would prevent damage seen from

snagging exposed coax connector.• – Adapter cable must be re defined to fanout to two 8w8DIN connectors ‐

(suggestion below)• – Need to sign off on all lengths and materials used

HF Upgrade StagingStage 1 (LS1)• PMT replacement• Upgrade cabling to allow transition to new FEE

and 2-anode readout• Use existing FE electronics.

– Adapter boards in readout boxes will gang anodes– Cable Adapters at FEE crates will adapt new cabling

to present electronicsStage 2• Upgrade FE electronics for 2-anode readout and

TDC– RoBox adapter boards changed for two 2-anode– Racks will be reconfigured for new FEE

• Maintain the possibility to switch to four-anode readout in the future should that prove necessary.

18

Working on the planning for 2013-14HF upgrade will happen in at least two phases:1. PMT’s will be replaced (LS1)

– Rebuild readout boxes (new PMT’s, PCB’s, and new cables).– Change HV power supplies in USC.

2. Front end electronics will be replaced (eYETS?) Prefer to do this – Reconfiguration of on detector racks– Additional LV[New backend electronics already commissioned]

Before, or at same time as electronics replacement:• Front end signal cables will need to be replaced• Additional fibers will need to be pulled

(3.) If not already done, double the channel count to fully exploit multi-anode PMT’s.

ROB work flow• Work starts as soon as HF’s are in garages and

boxes accessible.• Refurbishment will happen in SX5, HCAL alcove• Boxes will be processed in groups of “quadrants”,

9 boxes that make up 90 degrees in phi on HF.• Boxes will be remounted and commissioned by

quadrants (Smallest unit due to shared HV).• Burn in and commissioning happens whenever

services are available.– Off critical path. Have flexibility here

Conclusion In our regular plan the lifetime was

supposed to be after all the tests. However, we rushed it over the weekends since HCAL asked if any gain drop is observed. Over the 200 C, there is no gain drop. Now we have a dedicated box, it should go faster. We are hoping to reach 2000 C after new year. Our tasks is verify the Hamamatsu specs at 3000C.

Linearity has been tested with two different methods; single pulse and double pulse. On both of them we measure the PMTs to be within 1% linearity until ~9000 p.e.

Base-Board Testing

Conclusion• We “optically” tested all the boards with all bases

loaded.

• We got the signal from every socket. We measured the response uniformity.

• We also tested the bases for cross-talks with;

• 1 PMT lit the others covered

• 4 PMT lit the other 4 covered

• Alternated the lit-half

• In every case we did not observe any signal above pedestal on covered PMTs.

CU + BU

• For 2013 The CU group asked from their funding agency for support at CERN for four PhD students (experienced) for 6 months each and one new PhD student for 10 months.

They will be spending 50% of their time on LS1 work. • The 7 young faculty members (Kenan Sogut, Numan Bakirci, Sertac Ozturk,

Huseyin Topakli, Salim Cerci, Deniz Sunar Ceci, Bayram Tali) • They submitted a new project proposal to their funding agency in which

they are asking for 45 months of support both for 2013 and 2014. with 50% on the average time spent on LS1 activities.

• For 2013 the BU asked one more additional graduate student support during the LS1.
