HF UPGRADE PROJECT Y. Onel PM June 11,

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 10 PMT’s ( low gain, high dark current and black cover problems) to be tested by them. The Base Board production is also going well. Working on the New HV testing system and forming a committee to evaluate the RFP responses. Bulgarian new module testing is completed. (there were some problems- we are working on this- We expect the reworked proto will be at CERN soon).Waiting a detailed report from German and Alexi. Both power supplies will be 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. We have decided on the shield length- 54 mm (looks good !! the presentation by Ianos during HF meeting on May 14 th ) we will inform Mike Fountain to start with the production. Gain Sorting Proposal by Ugur is now ready. -A uniform gain distribution for one HF is outlined from the foist 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. 2

CAEN and Bulgarian PSU’s Two modules from CAEN A1535 and A1511. Both floating ground. A1535 – to power cathode circuit, A1511 – two last dinodes Both modules shows perfect performance up to the 3 mA current (max for these module). Presently A1535 has up to 3kV output. Needs to be reworked to have lover Voltage and higher current A1535A1511 Modified Bulgarian Power Supply – Power supply was modified to meet needs of new m-anode PMT’s. Lower voltage. Current up to the 10 mA. New firmware to fix the spike problems. Both power supplies will be tested and evaluated at CERN E-pool using professional equipment and high expertise level of pool technicians Between two oscillators within the same channel cross-talk was detected during the tests of Bulgarian PSU. Unit is back to Sofia, will be fixed and will be back at CERN by June 8th HV Board

Recent Highlights and News-II There 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 ( ).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. 4

Back-up 13

PMT test in 2012-I Iowa is planning is to have all PMT's at CERN sometime in Sept All of the PMT's and base boards will be tested in 2012 at CERN We are in process of defining all test-stand setups and needed equipment to handle the testing of the base boards and PMT's. WE plan on having setups to test the equivalent of two boxes worth of PMT's at a time. Burn in HF Plus Side ROBOXs in Garages 210 days Mon 3/12/13 - Mon 1/14/14 and Burn in HF Minus Side ROBOXs in Garages 9/21/13 (as defined by the HF Project Schedule). 14

PMT test in 2012-II Functionality test – All base boards will be equipped with PMT’s and PMT + base board assembly will be tested at CERN. Primary readout is with HCAL DAQ and HF QIE etc. We will have four light distribution boxes (three in addition to existing one).  Number augmented to allow base board + PMT testing in parallel with new ROB test development. Two will be set up for testing of PMT’s + base boards (6 base boards tested at a time).  In addition to light distribution unit, setups will have: “Dark box” cover Signal and HV cables ( At the moment we only have cables for the one upgraded box.) Support for Base boards + PMT’s (using production ROB parts) All the necessary equipment components are designed currently at Iowa. 15

PMT test in 2012-III Before majority of PMT’s will be shipped, we will have 24 m-anode PMT’s + three baseboards at CERN to assemble and test one more “upgraded” ROBOX for test- stand/testing development  Most mechanics already assembled at CERN.  Needs cables from Fermi box.  Will be assembled and ready for use by May. This ROBOX will be used to define all the test procedures –LED and PED runs, SPE runs. We will define what info goes to database, traveler runs etc. 16
