These are the files and responses I have received from KEK. I will try to keep this page current.

Response to some questions:
> What is the proper name of these tubes?
E3768 (Toshiba).
> Voltage and perveance for 75 MW?
~510kV and 0.78.
> Drive power needed?
>300W. (We currently uses a TWT at our test stand. Its maximum is 400W
feeding into the input cavity)
> Ion pump type, HV connector type?
The pumps installed on the KEK ppm tubes are
varian 911-5005.
This info was provided by Miyake-san, a Toshiba engineer.
> Water pressure and flow requirements?
Here are the numbers associated with our test stand:
Pressure;
IN 4.0kg/cm^2
OUT 1.0~1.5kg/cm^2
Flow;
We have 5 water circuits.
Collector ~50 litters/min
Anode+RFwindows 6 litters/min
Body 10 litters/min
Output Cavity 5 litters/min
Matching Coil very few (unmeasurable by a flap meter)
Here are the spec values of the water pressure and pressure loss (drop):
-------------------------------------------------------------------------
Part maxium pressure minimum pressure drop
-------------------------------------------------------------------------
Collector >10kg/cm^2, <3kg/cm^2
Body, Anode and Output Cavity >10kg/cm^2, <3kg/cm^2
RF window >4kg/cm^2, <3kg/cm^2
Matching Coil >10kg/cm^2, <1.5kg/cm^2
-------------------------------------------------------------------------
> Design of output flange, design of input flange?
KEK proper WR90 (female) flanges for both the input and output. I will post the drawing on the WEB location soon.
> Tube weight?
180kg. (Lead shelds not included)
> Is there any X-ray shielding design done?
Some have been done (Collector, body, etc). But not the whole.
