Moving Tape Collector (MTC)
A flexible tape transport system may be used to catch recoiling nuclei after
they have been mass identified at the focal plane
is 35 mm photographic film although other types of tape (eg. thinner tape
for charged-particle emission) may be used. Initially, one mass will be
collected and transported by the tape through 1.75 inch diameter tubing.
The tubing may be variable length depending on the experiment and may have
several counting stations along the way. The tape is stored in a
cartridge much like a ribbon on a printer. The stepping motor will
be computer controlled and will be able to run as fast as 10 m/s.
The overall set-up will be on wheels and special modules will be constructed
for "standard" experiments. Typical experiments involve gamma-ray
detection following beta-decay, conversion electron measurements, and
charged-particle spectroscopy. Future development projects involve the
collection of several masses and simultaneous counting.
This system is being built by Louisiana State University.
