VARIANTS OF NESTOR INJECTION REMOTE CONTROL

The two variants of remote control linac-60 for injection of the electron beam in the storage-ring ''NESTOR'' is
described. First variant of the autonomous remote control for linac design from the decoder 155ID3. In the second
variant use ADAM–4051 as encoder, while the decoders are the controllers ADAM-5051E, using for auto-loking
and plase control linac. The controllers help automation process diagnostics of this accelerator during its malfunc-
tion.
PACS: 29.17.+w
From the view point of control the linac-60 is de-
signed for the injection of the electron beam in the stor-
age-ring ''NESTOR'' consisting of 3 groups of objects:
the injector itself and 2 accelerating sections. For their
auto-locking and control, the section panel provides 2
controllers ADAM-5051E [1], which make it possible to
perform failure diagnostics of this accelerator during its
malfunction up to displaying the linac mimic diagram
with glowing dots on a computer screen showing the
location of the fault [2]. Equipment linac is arranged in
3 rooms: bunker, klystron hall and modulator basement.
And in an emergency it is important to know which way
to go and what take along with for fixing the problem.
Remote Control (RC) based on these controllers
seemed to us to be impossible as would distract them
from their primary functions: control the ljnac operation
mode and lock the main elements of its equipment at a
variation from the norm. Developed was the autono-
mous remote control (RC) circuit similar to that sug-
gested for modification of the linac-2000 RC circuit [3]
and having been successfully operating on the EPOS
accelerator at present [4].
Fig. 1. First variant RC linac-60: PО – operator control panel; 1S, 2S – section; Ph – phase; Аtt – amplitude;
G – >;L – <; SB, SA – button; C – the enсоder; LС – link; VT – level reduct; DC – decoder; [▬] – pauser
In the developed remote control circuit for linac – 60
(Fig. 1) diode encoder, the commands are transmitted
through a communication line to the section panel hav-
ing a high level where their levels are reduced to 5 V
(Fig. 2). Section decoders of the 155ID3-series are con-
nected as ''exclusive OR circuit", which makes it possi-
ble to use one button for the same type of commands,
reducing the size of operator control panel (software).
For phasing of high-frequency (RF) field of injector
step-motors of the type relay are used as a drive. Pulse
generator to them consists of a power supply unit
(PSU), self-oscillator and amplifier-shaper of current
signals (Fig. 3).
The feature of the self-oscillator circuit is the for-
mation of the last pulse of specified duration regardless
of the moment you release the control button "start " for
software (see Figs. 1, 4), which enables to precise run-
ning of mechanics and besides, unloads the final control
relays of the same type against heavy current switching
handing it over to starter "Start". The oscillator frequen-
cy is of 25…30 Hz.

In this regard, the stepped motor control is revised
so that not only address and object should be preselect-
ed, but also the direction of motion as in the ELA-40
[5]. In the section panel selection of the object for phas-
ing and movement direction is carried out through PAG,
the memory is organized through the final control relay
contacts of the phase shifter or attenuator. The delay line
for switching these relays are required to switch univi-
brator repeater PAG for having time to turn off the pre-
vious control, and the capacitor parallel to the relay coil
should extend the uni-vibrator pulse for correct opera-
tion of the relay. This difficulty can be avoided if, in-
stead of a relay to apply the integrated circuit switch.
Then the final layout of the remote control injector drive
"Nestor" will look like as in Fig. 4. The power module
is presented on Fig. 5.

Fig. 6. The second variant RC of linac-60: 1S, 2S – the section; HV – high voltage; Ph – the phase; Аtt – the ampli-
tude; G – >; L – <; SB, SA – the button; PО – the operator control panel; PG – pulse generator; RA – relay;
M – motor
The analysis of the phasing algorithm shows that it
consists of the operations of the address selection, sub-
ject to control, command of object parameter direction
control and command of self-regulation, viz. of the pre-
paratory and executive commands. If this principle is
extended to other subjects of the remote control, you
can still try to design a remote control by using the
ADAM controllers. In doing so, the hold time of con-
trollers by command preparatory part will be negligibly
small as compared to the process of the regulation itself
and will not significantly affect its basic function – lock-
ing. Then, as an encoder you can choose ADAM-5051
and load it with the above-mentioned set of controls
including algorithm preparatory part of remote control
(Fig. 6); and the executive part put on a separate link.
Here, communication with the computer is provided for
the organization of fault diagnosis linac.
