Data eXchange Coordination

• Ongoing Meetings with project engineers and experiments

• Compilation of summary report (EDMS 772011)

• Coordination of cabling

• Coordination of deployment of H/W

WP documentation EDMS 772011 v.3

Comments to 772011

• Thilo PAULY on 2006-10-02, 15:44 said: Accept Generally OK, but I have two major comments. Pages 4 - 5 - 7 - 10 -

• 5 Typo in caption for Table 2. 7 I'm confused about the number of fibres for TTC+BST, and it seems that the spares are not treated consistently in this document. 3.3: TTC = 5 signals + 1 spare 4.1: 6 TTC + 2 BST + 1 spare 4.2: Table 8: TTC 5 + 2 spares

• 10 First two bullets under status: Isn't the full VME crate requested by all experiments, in order to receive the safe beam TTL levels? To my knowledge ATLAS so far differs from other experiments that they have additionally requested (and received) a PCI-card (CTRP) for the GPS time-stamp.

EXPERIMENT BEAM INTERLOCKS

TTC instrumentation

BPTX beam collision timing

• Resolution @ 450 GeV/c ?

BIS beam interlock system

• BIC cabling provided to patch panel in rack specified by experiment (FoC).

• CIBU installed by AB-CO in rack specified by experiment (FoC).

• Cabling CIBU  patch panel tb provided by experiment. Connector and grounding specified by AB-CO.

• Cabling BICpatch-panel has been requested (DIC). TS-EL defined cabling campaign.

• CIBU available 1Q07. Installation and commissioning tbd between AB-CO and experiment DSS.

• Patch-panel space required 1U/channel.

• Question: is UPS required for CIBU?

• Are PPs needed?
• Totem CIBU location?
