Welcome to OrensteinLabKit's documentation!
============================================

OrensteinLabKit Python Module
==============================
OrensteinLabKit is a python module including all the functions which will be useful to the experiments in Orenstein's lab. The outline of OrensteinLab is listed below.

- Instrument
    - OptiCool
        - OptiCool_Control
    - Lakeshore
        - Lakeshore336
- Operation
    - ESP301
    - Attocube
        - v2
            - Attocube_v2
        - v4
            - Attocube_v4
- Measurement
    - Yue
        - Measurement


Installation
==============
OrensteinLabKit can be easily installed by pip install.

.. code-block:: python

    pip install OrensteinLabKit

Before using OrensteinLabKit, please remember to update the "configuration.txt" file in the module. The device ID of the lockin and the port ID of the ESP301 controller are required.

Instrument
===============
This section includes the home-written control programs of several instruments. These instruments don't have any developed python module/package to control, so I have to write the control programs by myself.

=====================================
Instrument.OptiCool.OptiCool_Control
=====================================
Control all the necessary operations of the OptiCool.

connect_opticool()
-------------------
No input. Return the telnet object connecting to the socket server of the OptiCool.

read_temperature(telnetObj)
---------------------------
Input the telnet object returned by connect_opticool(). Return an array [temperature, status]. The status means the temperature approaching status, which can be "Standby", "Tracking", "Chasing", "Near" and "Stable".

set_temperature(telnetObj, set_point, rate, mode)
--------------------------------------------------
Input 4 arguments, telnet object, temperature set point, ramp rate, mode. The highest ramp rate is 10 K/min. The mode has two options.

- 0: Fast settle
- 1: No overshoot

Return "command received".

read_field(telnetObj)
-----------------------
Input the telnet object. Return an array [field, status]. The status means the field approaching status, which can be "Ramping (Driven)" and "Holding (Driven)".

set_field(telnetObj, set_point, rate, approach_mode, 1)
--------------------------------------------------------
Input 5 arguments, telnet object, field set point, ramp rate, approach mode, field mode. The highest ramp rate is 110 Oe/s. The approach mode has three options.

- 0: Linear
- 1: No overshoot
- 2: Oscillate

The field mode has only one option in the OptiCool, but has two options in the PPMS and MPMS3. In this way, just use the value 1 for the field mode, which means "Driven".

Return "command received".

disconnect_opticool(telnetObj)
-------------------------------
Close the telnet object returned by connect_opticool().

==================================
Instrument.Lakeshore.Lakeshore336
==================================
Control all the necessary operations of the Lakeshore 336 temperature controller.

initialization_lakeshore336()
--------------------------------
Return the instrument object (inst).

read_temperature(inst)
------------------------
Input the instrument object obtained from initialization_lakeshore336(). Return the temperature.

read_setpoint(inst)
------------------------
Input the instrument object. Return the temperature setpoint.

set_setpoint(inst, output, set_temperature)
--------------------------------------------
Input 3 arguments, instrument object, output port number (1, 2, 3, 4) and temperature setpoint. 

read_ramp(inst)
------------------------
Input the instrument object. Return an array [on_off, ramp rate].

set_ramp(inst, output, on_off, ramp_rate)
------------------------------------------
Input 4 arguments, instrument object, output port number (1, 2, 3, 4), on_off (0, 1) and ramp rate. 

close_lakeshore336(inst)
------------------------------------------
Input the instrument object. Close the connection with the lakeshore 336. 



Operation
=============
This section includes some basic single-step operations frequently used in lab. The related instruments have developed python module/package to support, so the purpose of this section is just to make some basic operations easier to realize.

====================
Operation.ESP301
====================
Simple operations related to the ESP301 controller.

SingleStageMove(axis_index, pos, go_back)
---------------------------------------------

Corotate(axis_index_1, pos_1, go_back_1, axis_index_2, pos_2, go_back_2)
--------------------------------------------------------------------------

Read_Position(axis_index)
--------------------------

Balance_PID_single(incident_polarization_angle, P, tolerance, balance_axis_index, channel_index, time_constant)
-------------------------------------------------------------------------------------------------------------------

P can be extracted from Find_balance_angle in the Measurement section.

==================================
Operation.Attocube.v2.Attocube_v2
==================================
Simple operations related to the attocube controller. **Note: attocube axis index: 'x', 'y' and 'z'.**

Read_Position(axis_index)
----------------------------

SingleStageMove(axis_index, real_target, tolerance, go_back)
----------------------------------------------------------------

DoubleStageMove(axis_index_1, real_target_1, tolerance_1, go_back_1, axis_index_2, real_target_2, tolerance_2, go_back_2)
---------------------------------------------------------------------------------------------------------------------------------------


Measurement
=============
This section will include all the measurements in lab. However, different experiments may have different measurements to take, so I would like to create a subsection for everyone, so that group members can create their own measurement control programs. My measurement programs can work as examples. Please feel free to refer to them.

=============================
Measurement.Yue.Measurement
=============================

Lockin_time_record(channel_index, recording_time, time_constant, filename_head)
---------------------------------------------------------------------------------
This function simply records the data from lock-in amplifier in real time.

Find_balance_angle(incident_polarization_angle, axis_index, start_pos, step_size, num_of_steps, go_back, channel_index, time_constant, filename_head)
------------------------------------------------------------------------------------------------------------------------------------------------------
This function automatically finds the balance angle in MOKE measurement.

Corotate_measurement(num_of_steps, axis_index_1, start_pos_1, step_size_1, go_back_1, axis_index_2, start_pos_2, step_size_2, go_back_2, channel_index, time_constant, filename_head)
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
This function takes a single birefringence measurement.

Pump_probe(axis_index, start_pos, step_size, num_of_steps, go_back, channel_index, time_constant, filename_head)
------------------------------------------------------------------------------------------------------------------------------
This function takes a single pump-probe measurement.

Mapping(filename_head)
-------------------------
This functions takes a MOKE mapping.

Pol_scan_Mapping(filename_head)
--------------------------------
This functions takes a birefringence mapping.

Balance_PID_single(incident_polarization_angle, P, tolerance, balance_axis_index, channel_index, time_constant)
-------------------------------------------------------------------------------------------------------------------
This PID-based function automatically finds the balance angle in MOKE measurement. P can be extracted from Find_balance_angle.

Field_scan(set_points, ramp_rate, balance_axis_index, channel_index, time_constant, balance_channel_index, filename_head)
--------------------------------------------------------------------------------------------------------------------------------------
This function take measurements in an applied field. Set points need to be an array.

Field_scan_PID(set_points, ramp_rate, balance_axis_index, channel_index, time_constant, P, balance_channel_index, balance_time_constant, filename_head)
--------------------------------------------------------------------------------------------------------------------------------------------------------------
This function take measurements in an applied field. The artifact from Faraday rotation of the window is automatically compensated via PID. Set points need to be an array. P can be extracted from Find_balance_angle.
