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 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)

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.
Consists of 3 parts:
Four complete sets of cables were provided in advance of the October 2011 testbeam period.
Dual QIE board unit 2x24 channels =48 / unit
6U crates with 1.2” module spacing.
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.
Cable at front of racks
Critical choke point
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.
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.
Remove boxes from both HF’s
Remount on HF’s
Reception of cables
Installation / modification of cable storage
(continuity, & mapping)
Including other CMS subsystems
Cleaning and consolidation of existing cables and services
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).
Cable routing and storage
At upper level racks
Scaffolding for access to boxes and cables
Readout box removal/install,
Cabling inside outer shielding (ROB area)
Cabling at racks
Protection from activated areas may be needed
Cable routing and storage under floors
Removal of collars, CASTOR table.
Sourcing: will require ~1 week/HF where access to garages would limited
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)
ITU GROUP –KEREM CANKOCAK WILL APPLY FOR SABBATICAL for 2013
HF preparation and installation
They will be spending 50% of their time on LS1 work.
