Cyclotron

Tuning time estimates

Time estimates reflect average procedure times and do not account for unforeseen delays such as equipment failure. Procedural interruptions which are less than one hour are not captured. Such interruptions include, but are not limited to, machine configuration changes and tuning.

Startup and tuning after shutdown

Procedure	Time
520 MeV Cyclotron start-up	24 hours
BL1A [1]	+24 hours
BL1B [1]	+8 hours
BL2A [1]	+24 hours
BL2C [2]	+4 hours

[1] - Tuning the first high energy beam of the year will cause instability for all users. BL2A should be off or at low current when first tuning BL1A to avoid ISAC target damage.

[2] - Minor interruptions to other users when starting 2C4.

Startup and tuning after maintenance or beam development shift(s)

Procedure	Time
Maintenance	2 hours
Beam Development	4 hours
If Main Magnet has been off or Ion Source Filament or tune changed	+8 hours

Startup and tuning after switching beamline legs

Procedure	Time
BL1A<->BL1B	2 hours
BL2A2<->BL2A3	4 hours
BL2C1<->BL2C4	1 hour

Miscellaneous procedures

Procedure	Time
Establishing a tune for a new energy in BL1B [3]	4 hours
Changing energy in BL2C1 or STF target change at 2C4 [4]	1 hour

[3] - Not disruptive to other beamline users.

[4] - May be disruptive to other beamline users. Estimate includes downtime, start-up, and tuning time.
