Cryocooler Experiment Purpose: Measure cooler K Confirm drop-in mode, measure heat leak Update: 1 st series of tests completed in November Results were not conclusive due to some deficiencies in the test apparatus System was modified including addition of a larger liquid He storage vessel Recent poor performance in testing due to either bad cooler, convective currents between 1 st and 2 nd stages or thermal acoustic oscillations in piping These issues were addressed, and 1.5 W cooling power at 2 nd stage confirmed

MICE Spectrometer Solenoid Fabrication Update and Schedule StatusPage 22 Steve Virostek -- Lawrence Berkeley National Laboratory -- March 18, 2008 Overview (RFCC module) A bottoms-up, WBS based plan (including a cost estimate and schedule) has been developed for completion of two RFCC modules A task list of ~300 items includes: engineering, design, reviews, procurement, fabrication, assembly, testing and shipping Current plan calls for funding and/or effort from the following institutions: Lawrence Berkeley National Lab, ICST/HIT at Harbin, University of Mississippi, UC Riverside and Oxford Physics

MICE Spectrometer Solenoid Fabrication Update and Schedule StatusPage 23 Steve Virostek -- Lawrence Berkeley National Laboratory -- March 18, 2008 Funding and Schedule The early finish schedule and no contingency cost estimate results in delivery of the completed RFCC modules near the end of FY09 Currently projected funding may be sufficient to complete the project on the two year schedule Contingency and float can be provided by the use of FY10 funds and by stretching the schedule into FY10, if necessary RF cavity design and fab is on the critical path

MICE Spectrometer Solenoid Fabrication Update and Schedule StatusPage 24 Steve Virostek -- Lawrence Berkeley National Laboratory -- March 18, 2008 Preliminary Plan The detailed design of the cavities and associated subcomponents will be based on the prototype cavity design developed at LBNL and J-Lab The MuCool and MICE Coupling Coils have been designed and will be fabricated & tested at ICST LBNL engineering will coordinate the fabrication of the cavities using a combination of in-house shops, collaborator shops (U. Miss.) and outside resources (spinning, e-beam welding, etc.)

MICE Spectrometer Solenoid Fabrication Update and Schedule StatusPage 25 Steve Virostek -- Lawrence Berkeley National Laboratory -- March 18, 2008 Preliminary Plan (cont’d) Subcomponent procurements (Be windows, RF windows and couplers, vacuum system, cryocoolers, power supplies) will be specified by LBNL & purchased w/funds from various sources Coupling coils, cavities and other components will likely be integrated into RFCC modules at LBNL using in-house technical resources Module testing will take place at LBNL prior to shipping to the MICE hall at RAL

MICE Spectrometer Solenoid Fabrication Update and Schedule StatusPage 27 Steve Virostek -- Lawrence Berkeley National Laboratory -- March 18, 2008 Engineering, Design & Technical Resources An additional FTE engineer (Alan DeMello) at LBNL has been assigned to work on the module along with M. Green & S. Virostek ICST has the engineering and technical resources needed to complete the design and fabrication of the coupling coils (with some LBNL oversight) Technical resources, machine shops & assembly facilities are currently available at LBNL

MICE Spectrometer Solenoid Fabrication Update and Schedule StatusPage 28 Steve Virostek -- Lawrence Berkeley National Laboratory -- March 18, 2008 Funding Plan Projected available funding through LBNL (FY07- FY09), U. Miss. and UC Riverside may be sufficient to cover the estimated project costs ICST is funding the manpower & a portion of the raw material costs for completion of the coupling coils (bulk of material is coming from the US) The current cost estimates do not contain contingency - additional project $ to be available in FY10 should provide adequate contingency
