Polygon Physics SAS au capital social de 72 000 euros - 19, rue de Sassenage - 38600 Fontaine
SIREN 799 584 453 RCS Grenoble - TVA intracommunautaire FR 19 799584453 - APE 2899B
default network parameters: IP = 192.168.0.102 and subnet mask = 255.255.255.0
1. If the rack is off, switch on the rack and wait for 1 minute until the microcontroller is
initialized.
2. If necessary, set the IP address and subnet mask of the microcontroller with the command
set network <value1>/<value2> where <value1> is an IP v4 address and <value2> is the
subnet mask. For example, if I want to set the IP address to 192.168.0.17 and subnet mask to
255.255.0.0, the command is: set network 192.168.0.107/255.255.0.0
3. If your computer is running under Windows:
a. Go to “This PC”.
b. Under « Devices and drives », right click and select « add network location ».
c. Follow the steps, in the box « network or internet address », write the location of the
shared folder as: \\microcontroller ip address\SharedData. For instance, if the ip
address of the microcontroller is 192.168.0.107, write \\192.168.0.107\SharedData.
d. If your system requires a username, use pi (no password is needed).
e. The shared folder is now accessible:
i. The sub folder « data » contains all the measurements recorded while the
source is functioning. A new file is created when the command « set
rack_state 1 » is used or every 24 hours of functioning.
ii. The sub folder « log » contains the log files in which all the commands
received by the microcontroller and the microcontroller answers.
CAUTION
The sub folder « config » contains all the configuration files necessary to the proper
functioning of the microcontroller. Do not modify these files!
6.4 Manual ignition of the ion source
a) Regulate the source gas and preset the HV set point
To ignite the plasma in the source, it is necessary to use a gas flow rate which is typically higher than
the flow rate used for beam operation. Increase the gas valve setpoint to approximately 2.5V (for 0.5
bar inlet pressure) and wait until your pressure gauge indicates a stable pressure (the pressure should
be on the order of 5x10
-5
mbar but it depends on your configuration and pump system).
During setting the gas valve setpoint, turn on the UHF power to warm up the generator during the gas
stabilization time.
Apply also an ‘imax beam’ (typically 200 µA) and ‘imax focus’ (typically 80 µA) values to be able to use
the high voltages in the following.
b) Wait for the pressure and activate the UHF power
Wait for the stabilization of the pressure, then put the desired value for the UHF value.
