MTA Schedule and Priority Updates for RF Studies and Testing Initiatives

This document outlines the MTA schedule focusing on high-priority tasks such as vacuum RF studies, specifically on the 805 button cell and the 201 MICE prototype. Key points include the estimated timeframe for button runs, potential automation for efficiency, sample testing, and the complexities of parallel runs. Additionally, it addresses challenges with manpower and beam tests, along with the necessary reconfiguration and setup at MTA, including cryo-infrastructure and magnet setups. A clear schedule must be developed for upcoming tests, notably for August and beyond.

  1. MTA Schedule and Issues

  2. Schedule for MTA • Highest Priority goes to vacuum RF studies – 805 button cell and 201 MICE prototype • Button runs take about 3 weeks total • Maybe we can speed this up with automation? • We have 10 potential samples plus 5 or so from the UK • 45 weeks of data taking! • 201 running can for the most part run in parallel • But we have to move the 201 to gain access to change out buttons on the 805 • Second round of KEK convectively cooled LH2 absorber tests • We were attempting to do this in August (3 weeks), but we do not know if our Japanese colleagues can make it to Fermilab then • Muon’s Inc HP cell tests (their first draft of run plan – 22 weeks) • Some tests also need magnet • Requires 805 button cell to be removed • Manpower issue for fast turn-around • Beam tests – how and when?

  3. Schedule for MTA • Reconfiguration of MTA • Raise components to beam height • Install cryo-infrastructure • Transfer line system • valve boxes • Cryogen hookup to magnet • Estimate 3-4 month down time • Impact of Beam line installation during shutdown still not fully understood • Need to develop run schedule for August – July08 over the next month

  4. 201 MHz Cavity Operation in B Field • Initial 201 MHz operation in B Field • Limited to few hundred Gauss • Using Fringe Field of 4T magnet (in blue) • Need new vac pump to allow 201 to be moved right next to magnet • Gives 1T at window • Want to run with Coupling Coil as soon as it is available

  5. Reconfiguration of MTA • Need Coupling Coil (2.5T) MICE design • Shown in green schematically • THIS IS A CRUCIAL TEST FOR MICE AND FOR NF & MC in general • High Gradient RF operation in a magnetic field
