Monthly L2 Status Report -

WBS: Presenter:

• Complete planned developments of physics and geometry

modules of MARS15 for adequate modeling of backgrounds in MC detectors: new ROOT-based geometry is up and running; developments and tests of substantially updated electromagnetic shower (EMS) modules with precise modeling down to 1 keV are nearing completion.

• Higgs Factory (HF) IR lattice is almost ready for use within

MARS for MDI studies.

• HF IR magnet design is agreed upon.
• Finishing EMS module developments and tests in MARS.

Benchmarking showed amazing performance.

• Iterations done on the HF IR lattice and magnet designs.
• Timing and double-layer rejection studies finished for a 1.5-TeV

MC with latest ILCRoot version and showed these techniques to be very promising.

• Agreed on a HF detector design (SiD with CMS phase 2

tracker) and machine MDI study priorities (HF, then 3 TeV).

• Once a consistent design of HF IR quads and dipoles is

finished (in early January?), implement these into MARS along with a final (?) lattice; build the MDI model and prepare the first test runs with a toy detector.

• Start building a HF detector model under lcsim aiming at its

implementation to MARS in Q2.

• Q2: Build a complete consistent MARS model of the HF IR,

magnets, detector and preliminary MDI and magnet protection

• system. Perform first runs to address IR magnet performance

and background loads on sub-detectors. Prepare timing and double-layer rejection techniques for the HF lcsim detector model (if it is built).

• Q3: Optimization of HF magnet protection system and MDI.

Production MARS runs to feed the detector studies. With this source, launch full detector simulations (if the lcsim model built).

• MDI priorities changed from a 3 TeV MC to a Higgs Factory.
• Who will build a first lcsim version of a HF detector? SLAC?

Fermilab (Hans, Ron, Nikolai T. et al) with INFN help?

WBS: Presenter:

• -
• Email discussion on the 6d cooling demonstration issues
• Have got feedback from Bob Palmer only so far:
• 201 vs 805 Mhz: 805 is preferable, since 201 = MICE
• HW: will “inherit” at least one 805 MHz RF and two ~22 T SC sol.
• Relatively intense muon beam source: no feedback for now
• Note on intensity: RAL beam would not deliver many muons in 0.2

mm emittance. A study to see how to make such a beam would be worthwhile.

• Solicit more feedback
• Detail muon source options/parameters
• Seek potential synergies with NuStorm (in the framework of

MASS as well)
