EVAP is a simple Python 2 program to read and plot the data from the e-beam evaporator controller EVC 300 (FOCUS GmbH) as well as to set the parameters time dependent.
Tested on Ubuntu Linux 14.04 using a USB-to-RS-232-adapter and the EVC 300 controller. To connect to the serial port the python module Pyserial is used. For the GUI pywx, numpy, matplotlib and pylab are required.
In order to work properly EVAP needs read and write access to the serial
device (usually \dev\tty0 or in case you use a USB adapter \dev\ttyUSB0).
Start EVAP on the terminal by executing guievap.py.
If the controller is not found by EVAP an error message will appear on
the command line. As soon as the controller is connected and the Resume button is pressed
the values of the parameters will appear in the corresponding field.
The voltage and emission parameters can be changed directly within certain boundaries in order to protect the equipment. Moreover the emission current can be driven over time to make degassing more convenient (the main purpose of this program).
The plotted data for flux and emission can be saved in a CSV-file.
