REMARKS
G
HA coating
The R943-02 is coated with the conductive paint
connected to the cathode, which is covered with an
insulating material (HA coating). This method de-
creases noise. Care should be taken not to dam-
age the insulating cover wrapping around the bulb.
CAUTIONS
G
Use the HAMAMATSU SOCKET E678-21C or E678-21D. See "NOTES"
A
for cooling.
G
When soldering the voltage dividers to the socket, the PMT should be inserted in the socket.
G
Helium will permeate through the silica bulb, leading to an increase in noise. Avoid operating or stor-
ing tubes in an environment where helium is present.
G
As the R943-02 has a synthetic silica window, a very thin graded sealing structure is used in the
bulb wall. Although it is covered with an insulating cover, extreme care should be taken in handling.
