Glossary of Terms |
Energy Selection and Beam Transport System (ESBTS)
Includes those subsystems located between the degrader wheel and the entrance
of each nozzle. The Treatment Control System (TRCS) interfaces with the Energy
Selection and Beam Transport System both to degrade the beam up to the energy
defined by the range required to treat each patient and to correctly direct the beam
to the appropriate nozzle. The ESBTS includes 60º bending sections, straight beam
line sections, and Gantry sections. See also: Beam Profile Monitor, Energy Selection
and Beam Transport System, Treatment Control System.
Erasable PROM (EPROM)
Memory technology used to protect data from being lost even in the event of a
power failure.
External Coil Quadrupole (ECQ)
A type of magnet located in the Energy Selection and Beam Transport System. See
also: Energy Selection and Beam Transport System.
Facility
Includes the equipment as supplied by Ion Beam Applications (IBA), the building as
supplied by other subcontractors, and any other equipment installed by the
treatment center.
Fahrenheit (F)
A unit of measure used to indicate temperature.
Filter
A selective network of resistors, capacitors, and inductors that offer comparatively
little opposition to certain frequencies or to direct current, while blocking or
attenuating other frequencies. Alternatively, it could also be a piece of transparent
material that selectively absorbs some part of the light spectrum and transmits some
other part of the light spectrum.
Final Power Amplifier (FPA)
A component of the radio frequency system located upstream of the accelerator
(cyclotron). See also: Accelerator, Intermediate Power Amplifier.
First Scatterer (FS)
(Also known as fixed scatterer)
A BMD located downstream of ionization chamber no. 1 (IC1). It allows a
combination of six scatterers and/or three range shifters to be inserted or withdrawn
from the beam path. The thickness of each of the six scatterers and/or three range
shifters is arranged in a binary sequence so that, within limits, any required thickness
may be obtained by combination. See also: Nozzle, Beam Modifying Device.
