may be set to any value between 0.1 and 10 A/sec. The value can be
set by using either the numeric keypad per section 3.3 on page 29
or the fine adjust knob (section 3.4 on page 31). The default is 10 A/
sec unless preset by AMI to match a specific superconducting
magnet system.
3.10.2.12 PSwitch Cooling Gain
The default cooling gain of 0.0% may be adequate for the majority
of wet persistent switches. However, this setting may result in
some magnet drift during persistent switch cooling, especially with
conduction cooled switches. Increasing the cooling gain adds control
loop gain during the switch cooling cycle. Too little may result in
magnet drift during switch cooling. Too much may result in power
supply instability during switch cooling, which could potentially
prevent the switch from cooling. Most systems requiring some
cooling gain to control magnet drift will likely work with value set
to about 25%. The value can be set by using either the numeric
keypad per section 3.3 on page 29 or the fine adjust knob
3.10.2.13 Enable Quench Detect
The internal quench detection function of the Model 430
Programmer may be enabled or disabled according to the
preference of the user. The default value is NO.
A user input for
external quench detection
is provided on the rear
panel of the Model 430 Programmer
1
. The external input overrides
the internal quench detection function of the Model 430 and cannot
be disabled. For further discussion of the quench detection logic
and operation, please refer to section 3.15 on page 90.
