of the instrument in a consulting capacity.
TAK2- MAGNETICOPTICS I
The objective of this task was to develop and experimentally demonstrate an optical
alignment method for aligning the 180 degree bend achromatic magnetic section of the Ground
Test Accelerator. This work was part of the Neutral Particle Beam Program. Thomas A. Swann
was again Principal Investigator for this task, which involved 1 10 man hours of effort. A
conceptual approach was generated and refined by Mr. Swann under the direction of MEE-12
personnel and a simple experiment was conducted to verify that the approach was able to meet
the positioning tolerances required. The approach consisted of an optical instrument which could
simultaneously view with an alignment telescope three fiducials on each of the 1 7 magnets in the
180 degree array. The experiment conducted verified that the approach could meet the
positional tolerances required. A "White Paper" entitled Optical Device for Alignment of NPB
180 Degree Magnet Array, dated July 15, 1986, was subsequently prepared and submitted,
however, further funding to develop this approach was not allocated.
TASK 3- MAGNETIC OPTICS I
This work was also part of the Neutral Particle Beam Program. The objective of this
task was to develop magnet support and manipulation concepts for the 17 magnets of the 180
degree bend achromatic magnetic section of the Ground Test Accelerator. Edward J. Yavornik
was Principal Investigator for this task, which involved 760 man hours of effort. In addition to
the magnet support and manipulation concepts, which were developed, Mr. Yavornik also
participated in the preparation of the magnet specification control drawing and procurement
documents and accompanied MEE- 12 personnel in plant visits to evaluate prospective magnet
TASK 4- ARGONNE TELESCOPE
This work, which was also a part of the Neutral Particle Beam Program, involved design
support for the triplett magnet telescope assembly and its support structure. Edward J.
Yavornik was again Principal Investigator for this task, which involved 814 man hours of
effort. Thomas A. Swann also participated in this task. The entire telescope assembly consisted
of a 50 foot long vacuum beam line containing permanent magnet eyepiece and objective lens
assemblies. This was a large and heavy ( 1000 lb) unit and it was required to be manipulated to
microradian precision. Mr. Yavornik did the conceptual design for the telescope and worked
Here’s what’s next.
