WF/PC INSTRUMENT SCIENCE REPORT 92-02:
Estimation of the Current Status of the WF/PC UV Flood
by John W. MacKenty and Christine E. Ritchie
May, 1992
Abstract excerpted from the report:
A method of assessing the impact of decontamination procedures on the UV flood and of estimating the likelihood that the next decontamination will cause a return of QEH has been developed. Application of this methodology to the WF/PC-1 is presently limited both by the absence of a suitable pre-flood calibration and by some inconsistencies in the existing data. Although there is a strong possibility that systematic effects may dominate the present analysis and produce a completely misleading answer, the existing data suggest that the ~10 decontaminations carried out to date have removed only ~50% of the UV flood applied in December 1990 and that another ~5 flash style decontaminations are unlikely to reintroduce the QEH problem.
