Summary of the UK HARP Meeting held on Tuesday 5th September 2000 in Sheffield
Present: Chris Booth, Rob Edgecock, Malcolm Ellis, Alan Holmes, Richard Nicholson.
-
Target and Support
-
Support Arm: Two arms are currently being made in Newcastle.
They will be completed this week or next week.
After discussion, it was agreed that they should be brought to Sheffield, for the support cap
to be fitted.
Action: Alan to confirm delivery date, and arrange shipment to Sheffield.
-
Support Cap: The extra 20 mm length is causing some problems in supporting the tube
during machining, but Richard hopes to have these sorted out this week.
Up to date diagrams are needed by Mario Scandurra (and also Chris for simulation work).
Action: Richard to supply CERN, RAL & Oxford with new diagrams.
-
Targets: We have enough copper for the "thin" and "button" targets, and also the thick
target required next year.
Action: Richard to produce thin & button targets.
-
End flange: This will be ready in Oxford in about one week.
Alan will be away for a fortnight from the end of the week, but will supply contact details of
his replacement.
Action: Alan to confirm production date, and supply contact details.
It was agreed that all parts of the target support should be ready by about the 15th, ready
for shipping to CERN.
Oxford could arrange shipment at the end of the month, but this might be rather late.
Rob suggested shipment to CERN by the 22nd, so that it can be checked with the Inner Trigger Cylinder
before the latter is assembled.
Installation in HARP could not be until the second week of October.
Richard agreed to go out to CERN to commission the support system, remaining flexible to fit
in with the required dates.
Action: Rob to check with ITC people for possible date of test.
Chris to check with Lucie what workshop facilities are available for possible modifications.
-
Insertion Mechanism: Alan showed us preliminary designs for the rails and supports.
This is to be sent out for costing, even though some adjustment of dimensions is likely.
It should be ready by January, for installation at CERN in February or March.
Action: Alan to obtain cost estimates.
-
Special targets: A different method may be needed to mount the long targets,
especially for the K2K and Miniboone targets.
It was agreed to leave consideration of these until after the technical run.
-
Finances: Our financial situation appears to be reasonably healthy!
We have heard unofficially from Ken that funds will be available for further travel this
year and LTA in 2001.
Overall HARP costs must have increased by about 10% with the approval of the RPC.
We are not currently in a position to consider any extra contribution to the common fund.
-
Meetings at CERN: Chris gave a summary of the previous week's collaboration meeting
at CERN.
(Further details are available in the official minutes.)
He also outlined his progress in converting the target and support geometry description
from GEANT3 to GEANT4.
-
AoB: We need a Team Account for small expenditures during assembly and running.
Rob will contact Mary Elizabeth Shewry to arrange this.
Action: Rob.
-
Next meeting: to be arranged by e-mail.
