Useful stuff: grum.py, spreadsheet, links, etc.

GrumPy

grum.py is a python library to visualize data live (beta version). Check it here: https://gitlab.psi.ch/augustin_s/grum

To run it open terminal and type /sf/eido/bin/grum run and a window as the following appears:

To visualize the response of any sensor during a scan:

1. Define a sensor in slic: Open terminal and run slic. Then:

from slic.core.sensor import PVSensor, BSSensor

s = PVSensor("SOME-INTENSITY:FOR-EXAMPLE")

2. Do a scan. Example:

scan.scan1D(dummy, 0, 100, 1, 1000, "name", sensor = s)

3. Define a function to be applied to the selected channel (for now in the terminal):

def function_name(x):

return np.function(x)

and then:

s = PVSensor("SOME-INTENSITY:FOR-EXAMPLE", aggregation = function_name)

4. To combine the info from more than 2 channels, check this: https://gitlab.psi.ch/slic/slic/-/blob/master/slic/core/sensor/combined.py

Example:

    ...: from slic.core.sensor.conbini import Conbini
    ...: 
    ...: s1 = PVSensor("MTEST:COUNTER1", name="sin")
    ...: s2 = PVSensor("MTEST:COUNTER2", name="cos")
    ...: 
    ...: def f(x, y):
    ...:     return x**2 + y**2
    ...: 
    ...: c = Conbini("C", (s1, s2), f)
    ...: 
    ...: s1.get_current_value(), s2.get_current_value(), c.get_current_value()

How to open and create custom panels

To open a prepared panel open a terminal and type:

caqtdm /photonics/home/gac-maloja/caqtdm_test/panel_name.ui

Note the space after caqtdm.

There is already a prepared panel for the gige cameras:

caqtdm /photonics/home/gac-maloja/caqtdm_test/camera_generic.ui

To edit a panel you need to open caqtdm_designer:

caqtdm_designer /photonics/home/gac-maloja/caqtdm_test/panel_name.ui

To create a new panels the easiest is to start from a copy of the test file:

1. Go the to directory cd /photonics/home/gac-maloja/caqtdm_test/

2. Copy and name the new file cp test_0.ui new_name.ui

3. Go back to the main directory cd and type caqtdm_designer /photonics/home/gac-maloja/caqtdm_test/new_name.ui to open it.

How to get print out the values of controls to save them

1. Open Terminal
2. Type slic and run
3. Type print_line_for_spreadsheet() and run
4. Copy the values (right click / Copy, control+C does not work)
5. Paste them into a cell of an excel-like file
6. Select the cell go to the top menu/Data/Text to columns - Select format & click OK

How to change the parameters printed by print_line_for_spreadsheet()

1. Type and run gedit ~/git/maloja/spreadsheet.py or open the script directly in git/maloja/spreadsheet.py
2. Find the channels you want to add and their codes (right click on the display in the corresponding panel and "get info")
3. Add the corresponding name in the formatting of the output spreadsheet_line. The names that are at the beginning of the line are read, the rest (in series afterwards) are kept as empty spaces for user's manual input in the excel file)
4. Save and close and re-start slic

If you just want to print parameters in the Terminal you just need to run print_overview()

Other useful staff

• To acquire data slic / daq there are things is daq.*

• To run scans: slic / scan there are things is scan.* e.g. 1D 2D

• conda activate mdaq ~/checks/checks.py

• other option is to use gui -> slic / gui()

you can have a look a the variables just typing them exp_delay to add a new channel name= name("real channel name") and then you can do name.set (use tab) HOME / neat neat = slic / gui()

• To see available channels starting with some name: bs avail name

e.g. bs avail SATES

SATES20-CVME-EVR0:CALCI

SATES20-CVME-EVR0:CALCS

SATES20-CVME-EVR0:CALCX

SATES20-CVME-EVR0:CALCY

...

• To see where the channels are being recorded (computer) and other details: ioc records name.*

e.g. ioc records SATES.*

SATES20-XSMA165:MOT11:SET_ANG_ABSPOS calcout Reset rotational pos SATES20-CMOV-SMA5 maloja
SATES20-XSMA165:MOT11:SET_ANG_START1 calcout change value not actual pos SATES20-CMOV-SMA5 maloja
SATES20-XSMA165:MOT11:SET_LAST_SET calcout Hold the last position SATES20-CMOV-SMA5 maloja
SATES20-XSMA165:MOT11:SET_NONE_ABSPOS2 calcout Non sensor move SATES20-CMOV-SMA5 maloja

...

• To read channel values (live): bs receive ChannelName

e.g. bs receive SATES30-LSCP10:CH0:1
