Abstract

The signal to noise performance of spectrometer-J (Jabba) has been deteriorating since it was installed in 2009 July. The fault was identified as being a failed Schott KG4 short-pass infra-red filter. Since KG4 has been discontinued and no spares are available, it was decided to simply remove the filter and run with only the Schott RG9 coarse red pre-filter installed. Additional work identified a failed rain detector which was removed and returned to Birmingham, with a replacement to be shipped out as soon as possible. The batteries in the UPS were also replaced.
