iMICE Status of Selected Activities

• MICEUK Meeting
• 2nd May 2006
• Malcolm Ellis

2
Introduction

• Review of a few of the non-UK MICE activities.
• Almost all material is stolen from other talks at
  various meetings (MICE CM, VC, PCs and NFMCC CM).
• Areas touched on are
• Tracker cryostat system (Fermilab)
• Tracker electronics (Fermilab, IIT RAL)
• Muon Test Area (Fermilab)
• 201 MHz cavity at MTA (LBNL)
• CKOV I (UCL Mississippi)
• DAQ (Geneva)
• Frascati Test Beam plans (Geneva)

3
Tracker Cryo

• MICE VLPC Cryo
• 2 1024 Ch VLPC Cassettes in each system
• Two systems per tracker- 4 Total for MICE 1
  Test Stand
• Sumitomo GM Cryocooler
• Cold-end operating point at approximately 7K
• Cassette Gas system
• Lid Heater and temp control circuitry
• Vacuum pump

Prototype Cryostat

Cryostat Performance

• Typical Cooldown

6
Temperature Control

• Two stage Control
• Heat applied to 2nd stage of cryo-cooler (7K)
• Commercial Oxford temperature controller
• Heaters in cassette (1 per module) control to
  final set point (9K)
• System controls to better than 10 mK
• Spec 50 mK
• However running with 50Hz power (KEK), left
  cassette heaters were barely on almost no
  control from cassette
• Thermal link

1 Count1 mK

Cryo Status Plans

• The Prototype MICE VLPC cryo-system has been
  operated successfully for many months both at
  Fermilab and KEK
• All design specs have been met except for a
  left-right temperature asymmetry
• Thermal link design has been modified
• This will be tested as soon as the Fermilab
  shutdown is over (June 06)
• Cryo-coolers have been delivered
• Cryostat parts are on order expected delivery
  is mid-June 06.
• All systems will be assembled, tested, and
  commissioned by the end of the calendar year

AFEIIt Status

• The AFE IIt pre-production boards (15) have been
  tested to D0 spec
• The first boards came up very quickly
• In about 1 hour
• No green wires!
• TriPt testing is done
• Yield is about 80
• More than enough chips for D0 MICE Spares for
  both experiments
• Plus second pass could yield more
• Production Order released April 18th
• About 14 week lead for delivery of all boards
• But many will arrive earlier
• The critical issue for MICE is MICE-specific
  firmware development for AFE IIt
• NOT a Trivial amount of work

9
AFEIIt Test Stands

• The MICE IIT group has assembled an AFE test
  stand and will be responsible for testing left
  hand production boards
• Part of Negotiated agreement that led to D0s
  donation of AFE IIt boards to MICE
• In Addition an AFE IIt test stand has been
  assembled at RAL
• Board maintenance
• Firmware development

Results from Preliminary Test

• Conditioning started in late February 2006 with
• Flat copper windows (plates) with Ti-N coatings
• RF diagnostics
• Good vacuum high 10-9 Torr
• Without an external magnetic field, the cavity
  conditioned very quietly and quickly to reach
  16 MV/m
• Limited by available RF power.
• Test plan being developed
• External magnetic fields
• Achievable gradients vs magnetic field
• Curved Be windows.

DAQ Frascati Test Beam

• Preparation for the test of PID detector
  components and potential front end electronics at
  a test beam at Frascati in the summer.
• Stand alone DAQ is being built for this (not
  reusing UniDAQ system developed for KEK tests).
• Work being done at University of Geneva.
• Stand alone, local DAQ
• DAQ Reduced to minimum
• Local Start/Stop of Runs (no remote Run Control
  -gt no DAQ framework, no event building)
• Write data on local Disk
• Readout particle per particle
• No interrupts
• VME-PCI interface CAEN V2718 only
• Limited number of FEE modules supported
• TDC V1290
• QDC V972
• Only 2 Event types
• Particle Event
• Calibration Event

17
Status (19th April 2006)

• Manpower J.S. Graulich and 1 undergraduate
  student
• Software for V2718 80 done
• All fundamentals are done
• Read and Write in A32/D32,D16
• Read in BLT32, BLT64
• Basic I/O Register (2 Inputs, 5 Outputs)
• Software for V1290 80 done
• Only tested with V1190, should be easily
  transported to V1290
• Not fully commissioned yet
• Software for V792 40 done
• Work in progress
• Software for run control 25 done
• Working on User interface

18
First Results TBD

• Readout rate of V1190
• 27 Mbytes/sec in BLT64
• -gt 5 ms to read the full V1190 buffer memory
• (Readout of the tracker would require at least 40
  Mbytes/sec already obtained with BIT3 interface
  -gt we might have to deal with 2 different
  interface. No impact for BTF)

• I need some inputs
• Define needs for calibration
• Define needs for online monitoring
• Define needs for other FEE modules
• Tests of QDC FEE options will start in background
• Organize transport of my PC
• When is the test beam ?
