HBD Spring Update: Progress on Tracking, R&D Funding Requests, and Beam Options

The recent HBD update reveals significant advances in tracking with few new tracks observed due to noise suppression algorithms that recover the majority of noisy events. A funding request of $794,365 over two years has been submitted by the Tracking/PID consortium, involving Stony Brook University and the University of Virginia. The update highlights fiscal year challenges, including investments in new postdocs and future plans for heavy RICH development. Various options for beam acquisition from DESY, CERN, or SLAC are also discussed, along with improvements in detector technology.

Presentation Transcript

  1. HBD Update(brief!) TK Hemmick

  2. Spring Test: VERY few tracks • Avoiding the shadow of the local beam dump and other obstacles moved HBD out to about 40 degrees. • Overwhelmingly 4-scintillator-trigger is false coincidence. • Actual coincidence is pion dominated. • New algorithms for noise suppression recover majority of noisy events. Frodo and the One Ring ~100 tracks, 2Mevts Thomas’ Ring?

  3. EIC R&D Panel • Tracking/PID “consortium” requests $794,365 over two years. • SoLID Collaborators: (shared postdoc) • Stony Brook University, (TKH…) $153,404 • University of Virginia, (Nilanga, Kondo, …) $107,580 • Thomas Jefferson National Lab (Alexandre) <stuff> • ONLY major request recommended for full finding. • Fiscal Year Phase trouble: • Year One $$$ split over fiscal year (October). • Invest mostly in new Postdoc until October. • NOTE: EIC designs have light & heavy Fwd RICH. • No one is yet funded for heavy RICH R&D.

  4. Beam @...DESY? • Want a beam instead of scattered *(@)! • Options: • DESY (electrons, good access) • CERN (mixed beam, good access) • SLAC (electrons, poor access) • Shipping a live CsI-GEM??? • Jeb Ferrucci: Fed Ex “Custom Critical”. • Changes: • Segmented GEM to eliminate failures. • Detect Trips w/ capacitively coupled chain. • Hex-shaped pads & new software. GS: Stephanie Zajac UGS: Marie Blatnik UGS: Carl Cheung

  5. Mirror Makers • Big Mac Chamber: • 8’ diameter • 6’ tall • Currently: • Completed clean-out of “scattering stuff”. • Repaired large cryo-pump • 2 x 10-6Torr • Orders for electron gun, power supply, thickness monitor, etc… must wait for fiscal year boundary.
