CRYOSTAT SAMPLE ENVIRONMENT – basic options (always visible) Greyed-out if there is only one sample or only one temperature setpoint. Loop over sample first, then over temperature Loop over temperature first, then over sample Checkboxes are to enable or disable (grey-out) multiple sample positions as appropriate. Maximum of 3. Sample position The Sample Name entered by user in the top row gives the name (prefix) of the ascii file. “File prefix” field is now removed. “Fine position” is OFFSET from centre of sample. Temperature Setpoints Arbitrary number of set points can be added. Tolerance 0.1 K Wait time 60 s Ramping options to be integrated at a later date Add Setpoint Remove Setpoint
CRYOSTAT SAMPLE ENVIRONMENT – ‘advanced tab’ options Advanced Control Mode Manual PID Only likely to use these two most of the time. Note that when the control mode is changed, the Lakeshore sets the P, I, D parameters all to zero, so they must be re-applied. Zone control Open Loop Auto-tunePID Heater range Off 4mW 40mW 400mW 4W 40W Manual output 0 % Applies additional power on top of that calculated by the PID loop We will need to create new scannables for each of these, in addition to some others not shown on the Editor like Heater Output. Suggest to name them like this: ‘lakeshore_heater_output’ ‘lakeshore_control_mode’ ‘lakeshore_heater_range’ ‘lakeshore_p’ etc… 30 P 10 I 0 D
