General Points LQXB

• LMQXB is the responsibility of Fermilab
• MQXB quench and harmonics
• Alignment MCBX
• Bus work
• Relative Alignment of the MQXBs
• Mechanical alignment of interconnect pipes
• MCBX comes to Fermilab already tested cold (its
  cold performance is not Fermilabs
  responsibility)
• Cryostating of LMQXB
• Reference LMQXB magnetic axis to LQXB fiducials

General Points LQXA,LQXC

• MQXA is the responsibility of KEK/CERN
• On arrival at Fermilab we perform mechanical
  inspections
• Electrical checks prior to completing cold mass
• Mechanical alignment of CERN-supplied correctors
• Bus work
• Correctors comes to Fermilab already tested cold
  (its cold performance is not Fermilabs
  responsibility)
• Cryostating of LMQXB
• Reference LMQXB magnetic axis to LQXB fiducials
  (2 cold, the rest warm only

LQXB Acceptance Plan Approved

• Plan features
• Local Approval Process
• CERN Approval Process
• CERN Supplied Material
• US data transmitted to CERN
• Outline of criteria and tests to be performed
  prior to acceptance
• Ownership of equipment after approval
• Tests to be performed at CERN on arrival and
  prior to final acceptance

6
Status of LQXB01 Acceptance

• Local Fermilab MEB has met to discuss the
  acceptance. Report has been written on
  exceptions to meeting acceptance requirements
• Report has been sent electronically to Ranko
  Ostojic, prior to submission to the CERN MEB
• Fermilab has a proposed ID card. CERN (Ranko)
  has reviewed the ID card has proposed changes.
  We are still reviewing and negotiating the
  changes.
• Magnetic measurement data has not yet been
  transferred to CERN. This is expected soon.
• Note LQXB03 has been tested, and is ready for
  final acceptance

7
What needs to be done to ship LQXB01

• Finally electrical has been completed.
• The form for the final electrical needs to be
  finalized
• This form should be nearly identical to the form
  used for the reception at CERN (prior to the
  final acceptance)
• Shipping details are being finalized

8
Status of LQXA/C acceptance plan

• Acceptance Plan for LQXA/C not yet written.
• Should be a subset of the LQXB acceptance
  requirements, focused on issues related to
  completing the LMQX and the cryostated object.
  (room temperature electricals will be performed
  at Fermilab and should be performed at arrival at
  CERN)
• Needs to be completed before the first LQXA is
  shipped to CERN
• Need to discuss details of uploading KEK data to
  CERN database

9
Conclusion

• Acceptance plan for LQXB approved
• We are exercising the plan with the first (two)
  LQXB.
• Reception tests are outlined in the Acceptance
  plan. We need to provide details to CERN prior
  to magnet shipment.
• We need to write plan for LQXA/C
