Prototyping in the SPS using pickups equipped with LHC electronics

Meeting held on Friday 19-04-2002 - reported by Mike Lamont

Present : Lars Jensen, Joerg Wenninger, Mike Lamont

Agenda : Progress with the SPS prototype

From the hardware side:

1) All pick-ups installed
2) All cables pulled. Problem with coax cables for which the pairing of cables is out of tolerance. Currently being corrected (hopefully).
3) All racks installed.

Next steps for BI:
1) Electronics hopefully ready by the end of June. To start with we will equip two BPMs with a one plane measurement. The remainder added as the
front-end electronics become available.

Initial tests for BI:
1) The new TRIUMF acquisition card.
2) The TTC system with BST messages.
3) The WorldFIP control of the front-end chassis
4) All of this working together!


Discussion on situation in BA5.

It was noted that we had agreed to prototype global orbit feedback, using the standard SPS network in the first instance. The top end machine is to be qlsba3 (confirmed in place and running Lynx/OS 3.1.0). This machine will be responsible for acquiring and display the BPM data (in the first instance). If the network proves too flaky, we might look at using locba5 with dedicated connections.

Possibilities for 100BaseT connection to BA5...

Lars,

Sorry the controls network equipment does not allow any 100BaseT connections.
We simply do not have the hardware to do it in the SPS buildings.
Then the backbone does not allow fast data transfer.
The only exceptions have been made for the PCR and TCR where we have some
equipment that can supply this locally. However do not expect fast
connections with the outside as we "share" one 100Mb connection for all traffic.

You will have to wait for the SPS upgrade to see fast Ethernet.
