• Other

PARTICIPANTS: Bert Metzger, Rolf Ent, Amy Comer, Bogdan Wojtsekhowski, Hamlet Mkrtchyan, Hovanes Egiyan, Igor Strakovsky, Josh Crafts, Steven Lassiter, Vitaly Baturin, Dean Spiers, Tanja Horn

DESIGN/ENGINEERING OVERVIEW (Steven L.)

• 486 W blocks on site

• Coil procurement

• specification created - in discussion with TOKIN about specification and tolerances
• in discussion with TOKIN about specifications and tolerances - concerns about stated tolerances applied to geometric dimensions on flatness and parallelism; conductor cleaning
• CPS Tosca model updated to include bolt holes and cutouts

• Prototype (Dean)

• on site, machined and assembled

• Working on reqs for yoke and pole

• Yoke: 1010; pole: supermendur
• working towards deadline - beginning August for end of year clearance

• Insulation material and radiation hardness

• glass resin made for Japanese magnet
• max expected is MRad, but material should be resistant up to GRad levels

• Started discussions with Hall D about design models

MAGNET DESIGN/ASSEMBLY (Bert)

• Drawings almost done for yoke and pole

• identifying vendors

• Assembly steps outlined

• transport stand
• fasten coil to side yoke and shim; install
• fasten lower yole to stand
• check gap on coil
• add shims - mm of clearance to be accounted for
• fasten lower absorber - using alignment pins
• fasten side yoke assembly
• side yokes installed; fasten upper shielding
• check gap on coil and upper shield blocks, add shims
• add upper absorber and springs - still need to figure out pressure
• add flags to leads
• ready to be shipped to hall and can crane in place

• Testing cooling paths on 3 different models (see below)

• Clearances

• W blocks and cutting for special shapes

• Drawings for yoke assembly expected to be done in about a week

• Survey adjusters to align magnet; fine tuning with beam

• Length of leads will depend on amount of shielding - Gabriel is working on that

• Action item:

• check with Gabriel on status of the simulations

FLUENT CALCULATIONS - WATER COOLING CHANNEL ANALYSIS (Amy)

• Goal: compare Fluent compuration to by-hand for verification

• investigating 3 major designs with multiple cases

• results are very encouraging - ongoing work to interpret the details

NEXT MEETING: FRIDAY AUGUST 19 AT 8AM ET
