Discussions relevant to modifying
the reference design
Discussion of the polarizing beam splitter (current
design) versus a single magnetic-state selector and splitter (Wolfgang
Korsch) and Neutron Guide Optimizations
(Chris Crawford) (Wolfgang Korsch, Geoff Greene, Takeyasu Ito, Chris
Crawford)
Discussion (Josh
Long) of the high-voltage multiplier (current design) versus a 350-kV
supply and feed-through (Ernie Ihloff), Kerr Effect
in nEDM (Andrew Park) (Josh Long, Ernie Ihloff, Dima Budker)
Discussion of the pros and cons of the various
magnetic shielding systems – superconducting, ferromagnetic, Active Shield
(Riccardo Schmid), compensating coils, degaussing systems, and their
combinations. Shielding Factors (Brad
Filippone), Shield
Simulations (Mike Mendenhall) and Field
Uniformity (Septimiu Balascuta) (Brad
Filippone, Brad Plaster, Ricardo Alarcon)
Discussion of the optical configuration of the
measurement cell, i.e. powdered
versus deuterated styrene-embedded dTPB (Takeyasu Ito) and their relation
to light collection from the ends or sides of the cells. Related light guide issues. Impact of various high-voltage coatings. Silicon PMTs
(Vince Cianciolo). PMT afterpulsing
(Hans-Otto Meyer). (Takeyasu Ito, Paul Huffman, Martin Cooper, Vince
Cianciolo, Hans Meyer)
Discussion of adding NMR SQUID imaging to the design A
and B (Petr
Volegov/Bob Golub) and pictures I and II,. A justified
set of specifications is needed. Details on whether it is possible given the
diffusion the size of the thermal source that could be detected or expected,
implications for the magnets, and other details are needed. (Bob Golub,
Michelle Espy, Petr Volegov, Andrei Matlachov, Mike Hayden)
