1. OPERATION
1.1.
Operating instructions for transport ion getter pump source
The transport source is used for pumping any vacuum system with diode type ion getter
pumps (with a positive voltage supply) during transport.
The source allows to power a vacuum pumps with the working voltage of 5 kV and the
total current up to 100 µA.
·
The source is using the 9 piece LR14 batteries with total nominal voltage of
13,5V.
After connection of the HV output cables at the ion pumps switch on the main switch. The
operation is indicated by the weak whistling (the height of the tone is dependent on
immediate current of the vacuum pumps) and by flashing the lights on the Panel. The first
1 O s one red and one green light is flashing and then only some of the three green lights is
also flashing, that indicates the total current in both pumps in the fields of 0-10 µA, 10-50
µA,
or 50-100 µA. If there is an excess of total current over 100 µA (or short circuit), the
source is automatically shut down for a period of 1 min during that the red light is flashing
.
Then the source tries to start again
.
If the source is in use, it is possible to press the button (by the appropriate instrument) with
the BATTERY mark to display the battery status. The red light flashing means the
critical
batteries discharge (the voltage < 9V) and they need to be replaced as soon as possible.
The source automatically turns off if the battery voltage falls below 6 .5
V.
When using
alkaline batteries and the
total
current of pumps is 20 µA the source can work of about 16
days.
This period may also be adversely affected by temperature.
The operating parameters and historical record can be visua lized on PC via RS-232
interface with communication speed of 115 200biUs.
