== Tally components by systems [[media:200209_ResourceMeeting.xlsx]] ==

===Correctors (21 pairs , down from 23 pairs)===
*Will re-use existing MBH (long Haimson), MHB (short Haimson), MHD (on A1 cube), and eliminate MAD in favor of another type
*Total number of H/V pairs is 21 (goes down by 2 pair, so should free up 4 channels)

===Dipoles (2: same number)===
*PO written for 1+1 new 15 deg dipole fits on 3" OD pipe (replaces existing similar MDS fits on 2.5" pipe)
*500 keV spectrometer dipole (MBO) will either be re-used as-is, possibly modified for taller vacuum chamber aperture

===Solenoids (11: same number)===
*Gun to Chopper region : retain two FG solenoids + upgrade the FH, FB, FQ with three new FX solenoids
*Chopper : retain two FA solenoids captured to chopper cavities + upgrade the two FD solenoids with two new FY solenoids (TBD: one or two PS)
*Chopper to Booster : upgrade FA, FL with two new FX solenoids

===Quadrupoles (6: same number)===
*Replace existing 6 quads (types QW, QU) with two new triplets (3Q), under design now
*If design is late or does not come to fruition, may retain the 6 quads we have now
*Right now, retain one skew quad MQS0I07, but should be eliminated by improved Booster module

===Earth Coils (2: same number)===
*One coil across chopper
*One coil across chopper-booster

===Wien Filters (2: same number, Vertical then Horizontal)===
* PO written for 2+1 pairs of 200 keV coils to retrofit on dipole steel
* New electrodes under test at UITF

===Viewer/Camera combos (13: same number)===
* Same in each region, go figure
* YAG screens at TBD locations, metal markings on rear, metalized face for charge, Marcy getting bids from Radiabeam

===BPM's (15, up from 11)===
* Gun to Chopper : increase count by one, and we're thinking on a standardized 2.5" OD w/ Haimson for first three after gun
* Chopper to Booster : increase count by three, Phil is tallying available spare cans, need another BPM crate?!?  :(

===Harps (2, down from 3)===
* Gun to Chopper - one harp, removed an unpowered harp)
* Spectrometer - retain harp

===Current monitored apertures (8: same number)===
* Retain two insertable Faraday cups (PCUP, FC1); retain same hardware crash inhibit function
* Retain some one spectrometer dump (DL)
* A1 = retain, but would like remote linear control (has manual linear control)
* A2 = retain as-is, PSS function
* MS = retain, improve linear bellows
* A3 = retain, as-is PSS function
* A4 = retain, as-is PSS function

===Grounded apertures (4: same number)===
* Chopping apertures A,B,C on improved linear bellows assembly, with new stepper controls
* Central plug

===Cavity monitors (1: reduced by 1)===
* Gun to chopper - Remove Brock cavity
* Chopper to booster - Retain YAO cavity

===RF (same, w/o capture)===
* Prebuncher - existing SS or new Cu cavity; will need new amplifier, evaluating in GPT then convert to gradient/Watts
* Choppers 1/2 - same, new spare amplifiers purchased already
* Buncher - retain
* Warm capture - remove
* SRF - replace 5+5 w/ 2+7

===PSS (same number)===
* PSS kicker, retain - verify good for 200 keV at proposed location
* A3/A4 - retain as-is
* 500 keV dipole - modify limits for 200 + buncher keV inj seg mode only, and if dipole height increased

===Vacuum valves (7, increased by 1)===
*Gun to chopper - same three valves, but last viton valve VBV0I02 will become 2-3/4" all metal
*Chopper to booster - increase w/ new viton valve after chopper to improve vacuum isolation for venting chopper
*Spectrometer - retain valve

===Vacuum ion pumps (17, reduce by 4)===
*Gun to chopper - retain same number, using UHV supplies
*Chopping chamber - retain chopper cavities, reduce pump on chamber
*Chopper to booster - reduce by 4, should all be on capture
*Spectrometer - retain 1

== Bullets from last meeting... ==
* New 200kV small shed cathode electrode at machine shop (like electron at UITF)
* New gun 10" anode flange being designed to locate a steering coil closer to the gun
* Phil/Marcy starting to NEG coat vacuum chambers; need a 1kW sputtering PS that works (1 kV, 1 mA)
* [https://misportal.jlab.org/reqs/pr/viewPr.do?prNum=390977 PO] for 200 kV injector solenoids written (delivery April - June)

* Success applying +/- 20kV to UITF Wien!  Testing w/ better vacuum comes next...
* PO to be written for new 15 deg dipole next week
* Chase assigning new names for dipole and solenoids
* Starting to study which laser vacuum window to use 2-3/4" as-is, or 4-1/2"
* Curt waiting on kV spec for prebuncher @ 200 kV, for Watt in S.S. cavity
* Reza/Alicia/Dennis evaluating re-ordering of layout
* Looking at installing valve downstream of chopper #2 this down, possibly during fc#1 repair
* Gary Cheng inquiring about checking cryo lines between QCM and Booster
* 5D beam line will be removed
* Neil/Anthony working plan to build table to move QCM/Booster
