UNPACKING
Your Model 376/379 electron beam source crucible indexer is packed into a
specially designed double strength box surrounded with rigid foam padding.
Since packaging the indexer for safe shipment is otherwise difficult, please save
the box in the event that the indexer may ever need to be returned for servicing.
We cannot be held liable, and may not be able to fix without charge, indexers
which are damaged in transit as a result of improper packaging.
Inside the box will be the indexer, controller and this manual. Please check the
items to make sure no damage has occurred in transit. The indexer is ruggedly
built and packaged tightly so no damage should occur. In the event of any
deficiencies please report them to your vendor immediately. Also take care to

DESCRIPTION
The Indexer positions the crucibles of a turret-type sources, it also has a
position-indicating function. The Indexer features a high torque motor. It is
equipped with a coupling to accommodate a feedthrough drive shaft of a 1/4 inch
(6.35mm). The controller features crucible pocket selection lights to tell the
operator which crucible is in the “evaporate” position.
The model 376/379 electron beam source crucible indexer’s most notable
features are the following:
1Selects, accurately positions, and indicates crucible to be
evaporated.
2Indexes turret electron beam sources witha4to1gear ratio.
3Other features, such as heavy-duty screws in all important
fastening locations, and heavy-duty construction all round, are
designed to make the indexer serviceable for years of
production.
4Remote operation from a PLC (Programmable Logic Control).
5Can be tied to the high voltage interlock on the power supply.
6Ground stud, to ground the indexer from shorts.
7Sweep pattern select output
8Continuous and Banana Pocket operation (Model 379).

INSTALLATION
Required Components
See fig. 3-A
The following is the minimum list of components required for setting up the
indexer for safe operation.
14 or 6 pocket electron beam source. Source rotation must be in
working order.
2Vacuum system with adequate external room for indexer
mounting (see page 2-2 for dimensions).
319 inch rack with 115/230VAC, 50/60 Hz power to house the
controller.
4Cable from ground on chamber to ground stud indexer
controller.
Setting Up
There are many different ways to set up the indexer. The best location and drive
connection for your application can only be made after analyzing all the factors.
The determining factors for the location of the indexer are; source type (side or
bottom drive), free space in the chamber, and free space under the chamber.
The following installation options apply to both side and bottom drive sources.
See Fig. 3-A
The preferred way is a direct drive on each side of the feedthough, this eliminates
the problems associated with gear and chain drive. However the locating holes
and bolts of the feedthough, source, and indexer must be precisely
predetermined so the indexer can function properly. The Feedthrough Bracket
INSTALLATION 3-1
Telemark 376/379 Crucible Indexer

makes it easy to bolt the indexer to the bottom of the chamber with the nut of a 1"
feedthru.
With Telemark thru baseplate Sources (231, 238, 267, 268, 277 or 281) the motor
can be installed on the motor bracket.
With an internal chain drive the source can lined up so the pocket is in the center
of the chamber or new source can be fitted in an existing chamber.
External chain drives can be used when space under the chamber is at a
premium, it is best not to mount the indexer farther away than needed.

Installation

Changing Number of Pockets
See figure 3-B
Indexers are convertable between 4 and 6 pockets. The Switch Cover must be
removed. Move the junmper on J4 to the desired number of pockets. All the
jumpers on J4 must be across etheir “4pkt” or “6pkt”. The switch on the back
panel of the controller must match the jumpers on the Indexer Iso PCB.
Control PCB
See figure 3-C
The model 376 has C1 installed and not S1.
The model 379 has S1 installed and not C1. S1 is used to select the end of the
banana pocket, an in figure 4-1. The number 2 position is defalt as shipped from
the factory. For banana Pocket setup see operation chapter.

Sweep Select Control
See firures 3-C and 3-D
This option board is used in conjunction with sweepers incorporating pattern
preselect, such as the Telemark XY Sweep with the optional Sweep Select
Module. Switches S3 - S6 allow four sweep patterns (relay closesures on the
Sweep Select Control PCB, K5 - K8) to be married to any of the four or six pockets
controlled by the indexer. Push the DIP switch “ON” once for each of the pockets.
EACH INDEXING POSITION (POCKET) MUST HAVE ONLY ONE
SWEEP PATTERN SELECTED. SEE FIGURE 3-D
Four Pocket Sources:
Push the DIP switch ON to connect sweep pattern to connect sweep pattern to
pocket, ie. (S3) with all switches on gives you pattern (1) on all pockets. Only one
pattern per pocket is allowed. If pocket (1) is selected on S3 it cannot be selected
on S4, S5, or S6.

OPERATION
General Operation
Before using, first determine which materials are to be placed in the crucibles.
To set up the indexer, First rotate the switch to pocket one on the indexer
controller. Unplug power to the indexer to prevent accidental injuries. Then undo
the set screws on the coupler or drive gear. Rotate the crucible till the number one
pocket is lined up with the front of the source.
With the pocket lined up and the controller on pocket one, tighten down the set
screws on the couplers. Plug in power to the indexer, check to see that it is
indexing properly.
To use the desired pocket simply rotate the switch to that pocket. The light will
light-up when the selected pocket is reached.
The indexer is ruggedly designed and built, and should last a long time between
adjustments.
Model 379 Modes
The Model 379 Indexer has three modes of operation:
1Normal - In this mode it operates like a model 376.
OPERATION 4-1
Telemark 376/379 Crucible Indexer

2Banana - (see figure 4-A) In this mode the pocket will move
back and forth under the beam with one end of the pocket
being the #1 position and the opposite end being settable in
positions two to six. In the drawing the end is position #2. The
end position is set by selecting the position on S1 on the PC
board in the controller. See figure 3-C.
Note: 379 indexers are originally programmed at the factory for use with Sources
(sources) with a banana pocket that is the same as rotating between two pockets
(see figure 4-A, 1 to 2) 90 degrees back and forth. If a greater number of pockets
are traveled past then S1 on the main PC board must be reset. Remove the top
cover of the controller and with a small flat screwdriver make your selection of S1.
See figure 3-C for details on the setting of S1.
3Continuous - In this mode the crucible rotates continuously
(varied by the speed control). This is commonly used with a
trough type crucible.
