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 25 PMT’s ( low gain, high dark current and black cover problems) to be tested by them. We have shipped about 1000 PMT’s to CERN. 2nd900 PMT sorting is now completed and George et al will load the info in the HCAL DB. The PMT and Base Boards System tests with a QIE system has started at CERN-904.

  • We have approved the Base Board Production. (Reports from IOWA and CERN Tests are available)

  • Worked on the New HV system and formed a committee to evaluate the RFP responses.. Received a detailed report from German and Alexi.Both power supplies (CAEN and Bulgarian) were tested and evaluated at CERN E-pool using professional equipment and high expertise level of pool technicians.

  • The HV RFP and decision committee members are: Germain, Alexi, Ianos, S.Los, M.Miller, D.Winn from HF and Magnus and S. Lusin from CMS Coordination. The charge to this committee is written and we had our committee meeting on Friday August 3rd. The information provided by the HF Upgrade group was well received. There were some questions regarding Dynode 9-10 powering “Synchronization “ in the base board –S.Los has responded to this question. The decision is taken by this committee and we received the final recommendations by the PRR Committee.

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

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. Special thanks to Joel helping on this.

HF new front end integration was presented by Ianos to the HCAL as well as to the CMS TC. The HF Electronics Packaging as well as the agreement within HCAL that we should pursue the Winchester Cables presented by Terry Shaw.

Terry Shaw and Ianos have finalized the specs and they will be getting the quotes soon.

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.

Old pmt vs new pmt

Old PMTs(idleseveral years) exhibit systematic gain loss vs Integrated Luminosity, rate of loss slowing down.

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

Summary of components
Summary of components

Depends on cabling decision and final cabling connector specs.

Expecttoplace order by Oct1

* Production will be in batches spread out over the year. Expect >3/4 done by fall. Finished by end of year, but have few months contingency in early 2013.

Winchester cabling solution
Winchester cabling solution

Consists of 3 parts:

  • Cable for inside PMT Boxes,

  • 5m cables to FEE,

  • Adapters to connect to existing FEE

Assessment of winchester cables mechanical properties
Assessment of Winchester cables mechanical properties

Four complete sets of cables were provided in advance of the October 2011 testbeam period.

  • Diameter of cable ~2cm.

  • Minimum bend radius of ~10cm easily attained.

  • Cables are robust, and very pliable.

    Suggested improvements:

    • 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.

    • 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.

    • 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.

    • Would like grips on cable connectors to ease connecting/disconnecting.

    • Would like protection of the contacts to prevent damage during handling and installation.

  • Modifications discussed with Winchester in July. Essentially excepted.

Cable integration
Cable integration

  • Cable volume will substantially increase

  • Detailed evaluation was performed to confirm that the proposed solution was feasible given the space constraints within the HF shielding and support structures

  • (also for 4-anode readout).

Upper level cable storage shelves

Cable exit port in shielding

Critical choke point

Lower level cable storage under floor

Cable storage areas remain accessible when HF’s are in garages.

- keeps HF cabling off critical path of UXC activities.

Schedule scenarios
Schedule Scenarios

  • Purchase of the cables is subject to the spending profile

  • Scenarios:

    1) Purchase all cables within the next 3 months and be ready for installation during LS1. Later on, FE Electronics replaced.

    2) Purchase cables for single quadrant within next 3 months, Delay purchase of remaining cables into 2013, but in time to install at end of LS1.

    • Requires investment in infrastructure for testing/burn on the surface.

    • Pushes cabling and commissioning to end of LS1.

  • Put cable purchase off for X years, and install cables at time of FE electronics upgrade.

    • Uncertain when this could happen.

    • Big job, risky for a short shutdown.

Current status
Current status

  • Meeting with Winchester July 25

  • - Make quote good through Oct.2012.

  • - Two quotes, one for total cable purchase, another for all pigtails, and 50 long+adapter cables.

  • - Essentially accepted list of modifications.

  • - Delivery time of 3+ months.

  • - 75 ohm board mount connectors are in production (will be for 10 years). Simulation to be performed by Winchester.

Readout boxes on hf
Readout boxes on HF

There are 36 readout boxes on each HF for a total of 72 boxes.

Boxes are located at a radius of ~1.3m from the beam axis.

Each box houses 24 PMT’s and serves ~ a 10 degree slice of the detector.

(total number of PMT’s on HF is 1728)

All of these boxes are to be dismounted, reworked on surface, tested, and remounted.

Rob work flow
ROB work flow

Remove boxes from both HF’s


  • 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

  • Cabling will be performed in units of quadrants.

  • Ideally cable prep, and installation work is pipelined with ROB work to maximize testing, burn-in, and commissioning in the UXC.


Remove existing FE cables

Bundle, installation prep.

Re build rack cable supports

Estimate 1 week to cable a quadrant, two weeks for first one. ( 9 weeks total).

  • LS1 Start: Feb, 11, 2013 LS1 End: Nov 24, 2014

  • PMT Replacement: 27 Feb 2013 - 25 Mar 2014

  • HV PSU Replacement (USC): April 2013

  • Bring HF+ to its nominal position: 10 Sep 2014 - 22 Sep 2014

  • Bring HF- to its nominal position: 18 Sep 2014 - 30 Sep 2014

Hv installation
HV Installation

  • We plan to finish HV power supplies installation by May 1st, 2013 latest.Thisis based on the estimate that mid May could be the earliest to power the first HF quadrant.

  • Also based on availability of CAEN PSUs.

  • Alexi M. and + helper will finish the installation

  • German M. will commission the new system with existing PVSS.

  • ~1 week to do installation.

  • ~1 week for commissioning.

  • This planning assumes that the HF HV patch panel and interlock interfaces have been produced, tested, and ready for installation (as well as CAEN system).

Ls1 cabling
LS1 Cabling

  • We planned to benefit from LS1 to do as much as possible to prepare HF

  • for the future upgrade (multi-anode readout). During LS1 we target for the

  • following objectives:

  • Consolidation and clean up of cables and services. (~8 weeks)

  • Includes removal of existing front end signal cables

  • Includes the time spent on cables and services from other subsystems.

  • Modification, preparation of HF structures for cable

  • storage (~2 weeks)

  • Prepare racks as much as possible for future electronics. (~1 week)

  • Could be absorbed in consolidation step above (~8 weeks)

  • Install new cables (~1 week/quadrant + 1 week for first one = 9 weeks

Base boards
Base Boards

  • • 80% of Sockets are assembled and tested

  • • 20% of Adapter boards are assembled

  • • Base boards should arrive from assembly house by Sep. 10

  • 1. 80% of PMT sockets are assembled and tested

  • 2. 20% of Adapter boards are assembled

  • 3. Base boards have to be delivered from assembly house by Sep. 10

  • Further production plans

    As soon as we have Base boards from assembly house stop Socket assembly and switch to final assembly/testing of Base/Adapter board sandwiches (by that time we should have enough sockets for installation quantity of the boards – 216)

  • • 216 sets for installation should be ready by Dec.01

  • S.Los recommends purchasing the second set of board-to-board connectors for the future multi-channel Adapter board, before they become obsolete (~$3K)
