# Winston cone versus Trapezoidal lightguides: the current setup does not seem to be very robust: it includes a LED plus diffuser on one end of the baby cal and a PMT coupled on the other end via either lightguide using optical grease. Initial tests showed that trap/wico=0.8. A horizontal scan showed that max(trap)=max(wico), at different x positions. The setup needs to be improved, by ensuring that the diffuser system produces more uniform light. | # Winston cone versus Trapezoidal lightguides: the current setup does not seem to be very robust: it includes a LED plus diffuser on one end of the baby cal and a PMT coupled on the other end via either lightguide using optical grease.

- Winston cone versus Trapezoidal lightguides: the current setup does not seem to be very robust: it includes a LED plus diffuser on one end of the baby cal and a PMT coupled on the other end via either lightguide using optical grease. Initial tests showed that trap/wico=0.8. A horizontal scan showed that max(trap)=max(wico), at different x positions. The setup needs to be improved, by ensuring that the diffuser system produces more uniform light.
- FCAL block plus Plexiglas test: these are in progress, and a horizontal position scan has been measured.
- Review LED monitoring system: see George V's May 2010 presentation as a reference.
- Improvements to current design.
- Reduce size to 603 format (18x6 mm2).
- Improvements to current design.
