accelerator update
Accelerator Update
  • Continued progress on most fronts.
  • Mike Syphers is leaving the Lab in about a month.
    • Critical that we identify a replacement before then so there can be some overlap.
      • Discussions ongoing.
  • Pat Hurh has put us in touch with engineers from the high power target group at RAL.
    • They will be visiting next week to discuss possible contributions to LBNE and Mu2e
    • We are interested in having them work on the conceptual design of the production target, remote handling equipment and possible the heat shield.

solenoid update
Solenoid Update
  • Planning on a local review with some people outside of Mu2e at the end of June.
    • Chance to get some input on the direction we are heading.
  • Planning on design review with world recognized magnet experts in late summer/early fall.
  • Continued design progress on all fronts
  • Working on detailed quench calculations to understand the impact of increasing resistance in aluminum stabilizer as the result of radiation damage.
    • May not be as bad as originally thought, but still a work in progress.
    • Need an adequate safety factor.

building location update
Building Location Update

We have chopped about 30 m off the length of the beamline.

Length is driven by beam optics into extinction channel.

Would still like to get East of Kautz Rd.

simulations update
Simulations update
  • Dave Brown from LBNL has adopted the SuperBfastsim Monte Carlo to Mu2e and has implemented the T-Tracker geometry.
  • Dave has simulated the intrinsic resolution of the T-Tracker (energy loss and multiple scattering) and found it to be sufficient (~ 110 KeV).
    • Some cross checks still needed.
    • Pattern recognition errors and other more subtle effects can add non-Gaussian tails to the momentum function. These will be studied later with G4 and full pattern recognition and fitting algorithums. Not needed for CD-1.
  • Looking to make this tool generally available.
    • Can use this to answer many questions related to the detector at the CD-1 level.
    • Buy us some time to get full hit level G4 simulation in place for CD-2.
  • Still struggling with muon channel simulations
    • G4 implementation not ready
    • G4beamline (Muons Inc. product) not very flexible and author is busy on other things
      • Trying to buy some time from Muons Inc.

tracker update
Tracker Update
  • After significant discussion at the Collaboration meeting we have settled on a baseline configuration for CD-1
    • T-Tracker (decided several months ago)
    • Electronics in vacuum.
      • Preamp, updated BaBarElefant chip, TDC implemented in FPGA, ADC.
      • From MTBF for BaBarElefant chip we estimate about one failure every 5 years.
      • Looking for data on FPGAs.
      • Will eventually assess our threshold for missing channels/ groups of channels with simulation.
      • Could decide to move electronics out of vacuum if electronics failure rate too high or tolerance to missing channels too low.

daq update
DAQ Update
  • Mark Bowden is now the L2 Manager.
  • Our baseline concept is a streaming architecture that allows maximum flexibility while recording the same volume of data as in the standard triggered configuration.
    • Similar to other modern DAQ architectures
      • CMS, NOvA, NA62, LHCb

project controls
Project Controls
  • Our Project Controls person is no longer at the lab.
  • He was not a very good fit for what we are doing at this stage of the process.
  • We have 2 new people doing Project Controls for Mu2e
    • Larry Kirkpatrick
    • David Leeb
      • Still getting up to speed. Reconstructing existing files. Will begin meeting with L2 managers by next week.
  • Eventually will need 4 people doing Project Controls and EVMS
    • 1 for Solenoids and Muon Beamline
    • 1 for Accelerator
    • 1 for Conventional Construction and Project Management
    • 1 for Tracker, Calorimeter, CRV, DAQ
      • A mix of permanent Fermilab employees and contractors

project controls1
Project Controls
  • LBNE has a req on the street for a Project Controls person to set up their overall system and to lay the groundwork for hiring in several more over the next year.
    • 3 interviews scheduled.
    • I am on the interview team. If the 2d best person is good, I may consider hiring him/her to augment the existing staff.

R. Ray - Mu2e WGM

  • Working on Project Information Form (PIF) for ES&H.
  • Will continue our discussion at IPT meeting tomorrow about the path to a CX for Mu2e.
    • PIF will be important input.
  • Started work on Preliminary HA (required for CD-1).
    • I could use some help from someone with ES&H background.
    • Significant input needed from L2 managers about potential hazards associated with their systems.

Started writing CDR.

  • LBNE has 2 technical writers working on their CDR.
  • They could roll off in the Fall, so I may try to pick up some of their time to help with the Mu2e CDR.

action items
Action Items
  • Get L2 Manager for calorimeter in place – R. Ray
    • Still working on this.
  • Get resources required for CD-1 activities into P6. Begin adding relationships and developing BOEs – L2s/Walter Davis
    • Still a work in progress
  • Understand and document the magnitude of the heat shield problem – Coleman/Mokhov
    • Still looking at potential solutions. More optimistic this month than last.
  • Get moving on Electronics – Ron Ray
    • Nothing done in the last month. Meeting scheduled with PPD EE on Friday.
  • Complete set of requirements documents – Miller/Bernstein
    • Got commitments at collaboration meeting. Now have to get people to follow through.
