10/09/10FV 1 News and observations from Brussels' meeting

News and personal observations from the collaboration meeting Synchronization run in 2011 was widely discussed. A working group will assess its feasibility during coming weeks. Final decision will be taken during analysis meting at the end of October DCS funding for 2010 was approved by Steering Committee DCS WG presentation was positively received. The FSM and ORACLE are endorsed. More and more groups start to think about DCS (LAV, Straw, CEDAR) Extensive discussion of “common NA62” crate VF2 10/09/10

ALPHA Run in ≈Nov. 11 Equipment that could be Installed and used (partly):  7 to 8 LAV with partial readout  1 or ½ STRAW Tracker  CHOD ( Readout ?)  IRC (final), SAC (prototype)  LKR (SLM readout)  MUV3 + absorber wall  Vacuum system (various options possible) Closing vac. Tank > Straw 1. Vacuum continuation between Straw 1 and IRC tbd. Partial Vac. System (target mbar)  Electronic racks (partly)  Temporary TDAQ system, but (prototypes) final components (LTU, TEL62,…) What can we realistically achieve ? 07/09/ FH 3 ALPHA-RUN 2011

Beam Option (1) Run with Muons. Hadrons stopped in TAX. After Straw 1, no beam tube, MNP33 off. Optional vacuum up to STRAW 1. Beam dump ( not needed) 07/09/ FH 4 ALPHA-RUN 2011

There is request to integrate threshold settings and reading (LAV). Apparently it was done in LHCb. Probably some “off the shelf” solution already exist (see LAV slides) Unfortunately some groups are coming with request of non standard equipment integration: o CEDAR feedback loop for chiller temperature control HV: Propose building a 30 + channel HV supply as a double-width 6U VME module. 8 modules / crate plus VME CPU with Ethernet for remote control. LV Supplies: +/- 5V to each sector from VME module We should be ready to collaborative work (common programming standards, documentation, etc). VF5 10/09/10

6 LAV: DCS requirements FEE boards The structure of our slow control system consists of 4 CAN line : 1 for Crate VME9U 1 for Tell62 1 for HV system 1 for 8 Front End board

7 LAV: DCS requirements FEE boards 1) VME 9U crate Monitoring Items Reading cycle per Status ON/OFF/Error 30 sec or even more Voltages/currents 30 sec or even more Crate temperature 30 sec or even more Fan Speed 30 sec or even more Actions: ON/OFF/Rest communication 2) TELL1 Monitoring (Ask Marco Sozzi) 4) FEE Monitoring dedicated CAN-Open line (8 boards) Monitoring Items:Reading cycle per Status ON/OFF/Error30 sec or even more Voltages30 sec or even more Boards temperature30 sec or even more Thresholds (2x32 ch L/H)30 sec or even more Actions:N channels Set threshold value(2x32 ch L/H) Set test pulse signal 3) HV Monitoring (to be defined)

HV – about 16 channels needed (4 – IRC, 6-9 – SAC) o Can use a standard market HV supply o An alternative solution is under consideration: HPD HV for CMS 2000V, Imax=1mA, Stability – 1V, pusations ~ 5mV. Price ~3000 euro per 16 ch, including crate + controller (RS232) VF8 10/09/10 IRC and SAC
