The Czerny_Turner Instrument
Czerny-Turner monochromator.
Identification
- Site: BARC
- Author: Stephane Bac, Antoine Padovani
- Origin: Synchrotron Soleil
- Date: Jul 21st 2022
Description
This Czerny-Turner monochromator was built from "Design and fabrication of a Czerny-Turner monochromator-cum-spectrograph" by Murty, M.V.R.K.; Shukla, R.P.; Bhattacharya, S.S.; Krishnamurthy, G. (Bhabha Atomic Research Centre, Bombay (India). Spectroscopy Div.) Bhabha Atomic Research Centre, Bombay (India) 1987 It can be found here: https://inis.iaea.org/collection/NCLCollectionStore/_Public/19/019/19019134.pdf Example: Do a scan (scan parameter =1) from x_screw=20 to 103 mm. The calculated monitor "Wavelength(Ang) as a function of x_screw(mm)" will be a linear function. The monochromator functions properly.
Examples
(Test cases in bold)- Test: x_screw=60 Detector: w_monitor_I=0.0721
- TestScan: mxrun Czerny_Turner.instr -N21 x_screw=20,103 scan=1 -n1e6 Detector: Wavelength_I={21 values}
Input parameters
Parameters in boldface are required; the others are optional.| Name | Unit | Description | Default |
| x_screw | mm | Displacement perpendicular to initial position of the lever (sine drive mechanism) | 0 |
| scan | 0 or 1 | 1 is to activate wavelength monitor while scanning the x_screw parameter | 0 |
