the Shutter Delay parameter equal to the delay

Source Voltage - This parameter must be set to correspond to the input

voltage range of the source power supply (0 to 2.5, 5.0 or 10.0 volts).

tings of the rest of the source parameters are dependent on whether the

has one or more pockets (crucibles) and whether pocket selection is

or automatic.

gle Pocket Source - If the source has only one pocket (single pocket E-

beam gun, filament boat or sputtering source) then the remaining
parameters can be left at their default values.

position control of a

message will appear at the start of each layer instructing the operator to
change source N to the required material.

ltiple Pocket Source with Automatic Position Control - There are two
parameters requiring definition which are common to all the various types

osition control. The first is the Number of Pockets parameter and the

ond is the Rotator Delay parameter. The Number of Pockets parameter

imply the number of pockets in the source. The Rotator Delay

ameter defines the maximum amount of t

pocket to rotate into position. This should be set to the time it takes for

ator to go from pocket #1 all the way around to pocket #1 again.

ttings of the three remaining parameters required for automatic

t position control depend on the required type of p

position feedback.

on Control - The MDC-360 can be setup to either control the pocke

n directly by interfacing to the rotator’s actuator or indirectly by

cing to a rotator controller.

Control of Pocket Position - Direct control m

will be created called “SourceN Drive Up” that should be connected
between the rotator motor and power supply.

direction. Select Fast for the Drive parameter. Two relay outputs
will be created. One called “SourceN Drive Up” and one called
“SourceN Drive Dn”. With this drive
