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 spare4.1: 6 TTC + 2 BST + 1 spare4.2: 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.

Jorg WENNINGER on 2006-09-30, 11:03 said: Accept Ok - except that I'm not in charge of supplying the mode (or even impleneting it). That is more a general LHC Control System issue.

Daniela MACINA on 2006-10-02, 10:05 said: Accept The functional specifications about the experimental interlocks (EDMS 653932) say that the movable devices can move from their garage position when beam is STABLE or UNSTABLE. In addition, during UNSTABLE beam the near detectors are supposed to move as fast as they can to their garage position. It is not clear to me that the GMT system provides to the experiments the SAFE information about UNSTABLE beam (it provides it only on STABLE beam). This issue should be clarified as soon as possible since it is fundamental for the operation of the movable detectors. Pages 4 - 5 - 4 I am not anymore the link person for TOTEM. The new linkperson is Walter Snoeys.

5 Line 4: harwired injection inhibit is also present on the position of the movable devices since the interlock on the position fully exploits the functions of the BIC.


EXPERIMENT BEAM INTERLOCKS

Beam abort and injection inhibit signals can be generated by each detector and each experimental magnet.

Beam abort requests are transmitted over hardwired links to the beam interlock system.A hardwired injection inhibit is presently only foreseen for the ALICE ZDC acting on beam 1.All other injection inhibit requests use the DIP system links.

Id Supplier Project Eng Scope of supply

1 Experiments E. Sbrissa Exp. Magnet interlock – cabling from MSS to BIS.

PH-DT1 (E. Sbrissa). Application. Only Alice & Lhcb dipole magnets concerned.

2 Experiments Link persons Beam abort. Cabling to BIS (CIBU, BIC),.

Experiments Link persons provide a coherent signal

3 Experiments Link persons Injection inhibit. All S/W flags over DIP except for ALICE ZDC H/W contact.

4 Experiments Link persons Confirmation flag over DIP for Rdy for adjust/Rdy for dump.

Sbrissa would install the correct cable between the BIC and his CIBU. E. Sbrissa is ok with someone doing it for him, however, and will supply the final rack location ASAP.
