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 i
on
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
1Os one red and one green light
is
flashing and then only some ofthe 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 visualized
on
PC via RS-232
interface with communication speed
of
115 200biUs.
