To carry out crossed-field secondary emission electron sources scientific-research developments we have designed and man-
ufactured a 12-channel information measuring system. A hardware complex of the multichannel pulse-signal recording system is
built up from a personal computer, crate CAMAC with modules, an interface unit and a synchronization system. The software of
information measuring system operates in the Windows environment.

1. EXPERIMENTAL SETUP AND RE-
SEARCH METHODS
Experimental set-ups developed for investigations at
the "Accelerator" R&D Production Establishment com-
prise: vacuum chamber with an assembly of secondary
emission metallic cathodes under investigation, pulse
high-voltage generator, assembly of magnetic field gen-
eration and measuring system. In the choice on the
methods of measurement, it has been taken into account
that the object has the following characteristics:
the output beam of the gun is a set of parallel electron
annular beams with d from 5 to 8 mm (8 beams at the first
stage) arranged on the diameter D=44 mm (the number of
beams and their mutual arrangement may vary);
total pulsed current of all the beams about 100 A;
current pulse duration - from 1 to 5 µs;
pulse-repetition frequency – from 1 to 12.5 Hz;
electron energy – up to 50 keV;
the electron beam source and the collector are in the
constant magnetic field from 0.1 to 0.25 T.
The schematic diagram of experimental setup was
gave and described in paper [1] In Fig.1 are shown the
system under investigation with cylinder anode and sec-
ondary-emission cathodes inside of anode. There are 8
copper secondary-emission cathodes (3) of 5 mm in di-
ameter in the system. Cylinder diameter of the external
anode (1) is 68 mm, cylinder diameter of the internal
anode (2) is 20 mm. The anode cylinders are fabricated
from stainless steel and are connected together with the
help of metallic flange with holes for cathodes. For
study parameters of each beam in detail are used section
cooled Faraday cup and automated 12-channel informa-
tion measuring system. The beam current is measured
simultaneously for each beam The number of Faraday
cups is equal to the number of beams.
Fig. 1. Multicathode system: 1, 2 – anode;
3 – secondary emission cathode
The electrons that have missed the cups arrive at a special
insulated metal mask, which also serves as a collector.
To study space and time homogeneity of one beam one
of the Faraday cups is overlapped by a special silver screen
with a thin (∆=0.5 mm) radial slit. This allowed to estimate
of beam transverse size during observation of beam glow.
The signals from each of the Faraday cups and
masks via coaxial cables arrive into the block of
matched attenuators. The passband of channel is
350 MGHz. The block of matched attenuators makes it
possible to match the amplitude signals for the subse-
quent conversion in ADC. The Faraday cups are cooled
by contact through a thin insulating spacer with a water-
cooled metal plane. A special channel with a passband
of up to 12 GHz was provided for investigations of mi-
crowave signals arising during the gun operation.. It
consists of an inductive probe and of a coaxial line with
a wide-band coaxial connector. A simplified layout of
the Faraday cups is shown in Fig. 2. Each author should
submit all of the source files (text and figures), the post-
script file and a hard copy version of the paper. This will
allow the editors to reconstruct the paper in case of pro-
cessing difficulties and compare the version produced
for publication with the hard copy.

2. INFORMATION MEASURING SYSTEM
(IMS)
To carry out above-described scientific-research de-
velopments we have designed and manufactured a 12-
channel information measuring system. IMS makes it
possible to measure the amplitude-time characteristics

of signals, operative processing of acquired data and
recording the information obtained on magnetic disks.
2.1. HARDWARE OF IMS
A hardware complex of the multichannel pulse-sig-
nal recording system (Fig.3) is built up from a personal
computer (PC), crate CAMAC with modules, an inter-
face unit and a synchronization system.
Fig. 3. Block diagram of the multichannel pulse-
signal recording system
Pulse signals are recorded by means of three special
ADC and generator-synchronizer (GS) with a discrete-
ness of 50 ns or 100 ns simultaneously from 12 channels.
Each ADC module contains four independent chan-
nels. The memory capacity of each channel is 16 K. For
the development we have used a microcircuit of the firm
Analog Devices (AD 9200). The dynamic range of mea-
surement on the amplitude is 0, -2 volts.
The number of discreteness levels on the amplitude is
256. The amplitude characteristic of one module is given in
Fig.4. The equipment is entirely made in accordance with
the CAMAC standard. The operative information is dis-
played on the color graphical display of the PC (Fig.5).

one from the ADC modules
2.2. SOFTWARE OF IMS
The software of IMS operates in the Windows envi-
ronment. It was written with the use of a visual object-
oriented programming system C++Builder 5. With the
help of special menus (see Fig.5) the researcher can pre-
set a time interval of measuring, quantity of pulses mea-
sured and discreteness frequency, specify a number of
measuring channels and choice a single or cyclic mode of
measuring. After finishing the measurement cycle for
each channel the following is displayed (see Fig.5):
mean amplitude of the measured pulse train (A) in
relative and physical units;
coefficient of maximum pulse amplitude deviation
from the mean value (Km%);
mean pulse duration Tp and delay of the pulse leading
edge Td relatively to the synchropulse;
mean value of the area under the pulse – Sum.
The plots of time characteristics of measured pulse
trains and the histograms of distribution of charges from
the Faraday cups connected to the first ten IMS chan-
nels are displayed at researcher’s will. Using the light
button “Page” one can survey all the pulses of the train.
For the subsequent processing the researcher can
store the measured data complementing them with his
commentaries.

Engineered system may be used for recording of in-
telligence signals from pulse linear electron accelerator
and other experimental setup.
