Booster Radiation Damage Facility (RDF)
Some HistoryThe Radiation Damage Facility originated in the AP4 beam line, used primarily for testing the D0 Vertex Detectors.
The advent of the MI8 line and the MI precludedfurther use of the AP4 dump for this purpose.
The present facility was constructed in the 8Gev transfer line enclosure between the Booster and the Main Ring / Tevatron.

RDF Beam Characteristics
Charge per Hour = 5.2e15 protons/hour
Charge = # pulses/hour * Intensity/pulse
Ex 1200 * 4.3e12 = 5.16 e12 protons
Minimum Charge per pulse ~ 0.25e11 protons
Dump Annual Limit = 3.8 e 18 protons
Beam width is typically ~25 mm H & V
RDF Operations
The RDF facility is operated from within the Beams Division.
Use of the facility requires submission and approval of a formal written RUN request to the RDF Safety Committee. This committee makes a recommendation to the Beams Division Head who has final approval of a run.
There are limits…..
-- Beam requires dedicated operation.
-- Available beam time during HEP is virtually non
existent.
-- High intensity irradiation of dense targets unlikely to be
approved.
-- We provide the beam, the users provides everything else.
