1. Cryotarget Training
Common Target Training for Halls A & C for the 12 GeV Era
A trained TO must be on shift whenever the target is liquified
Tgt Ops as they have been for >20 years

2. 12 GeV Target Training Requirements
For all new TO’s:
Oral Training course
Practical:
training in CR with an expert & a cold target
~ half shift shadowing a trained TO
For already-trained (in 6 GeV era):
Training course
recommend to attend oral training class
must at least read training slides online
short training review in CR with expert
Training in Hall A is good for Hall C & vice versa

3. Training Ingredients
List of what the TO must know how to do, & what’s done by the tgt group/experts
Who are the experts & how to reach them
Basic target anatomy & goal parameters
How to run the tgt GUIs & Alarm Handler:
reboot tgt IOC, query archiver, interpret strip charts, change targets, adjust coolant, recognize developing problems, etc.
How to handle off-normal events

4. Some Resources Users Guide to the Hall C Cryotarget: 
Hall C cryotarget web page: 
Hall A/C Target Training Talk: 
Hall C Operational Restrictions: 
Hall C Target Archiver: 
Tgt expert on call 24/7 when condensed

5. Main Target Control GUI
IOC Heartbeat
Alarm Handler
ESR
Secondary GUI buttons
Strip Charts
Parameter colors keyed to ALH (green, yellow, red, white)

6. Strip Charts

7. Alarm Handler (Audible & Visual)
CTARG

8. Operational Restrictions
Limits set ahead of time by a designated expert.
TO’s must check this before putting beam on a new target.
MCC is also supposed to check IBEAM & Raster for new targets.
Target ion chamber calibrated for each target.

9. CR Hardware Dedicated tgt computer & monitors
Raster scope, beam current display
Kill switches
tgt motion, heater, JT valves
Sirens
Low H2/D2 pressure, SC vacuum
Analog H2 temperature readout
lifeline during IOC reboot, network outage
Analog auxiliary heater control
can manually stabilize tgt in off-normal situations

10. Live Target Status on your phone!
Very useful, especially for Tgt Experts. Can diagnose problems quickly, from anywhere, when called.

If you need help, call on-call person 1st (posted in CR),
then these people in the order listed.
(use home # only as a last resort if off hours)

13. High Loop Temperature Alarm
No real danger. Just delays.
Ask MCC to turn off the beam
Check other TS’s, & analog temp. r.o.
If just PID TS  change PID TS
LH2 Pump tripped? Restart.
HPH should 0W. If not turn it off.
SC vacuum OK?
Turbopump tripped? Call tech-on-call (Hall A or Hall C)
Coolant Tsupply abnormally high?
Close offending JT. Reduce pump speed.
May be ESR/CHL or xfer line IV failing…
