I will describe a project which would enable the measurement of leading protons in events triggered by the CMS detector and observed in the Roman Pots of TOTEM- even at LHC design luminosity. I will focus on studies done with deep-depleted APD's used to directly detect charged particles with a resolution in the few picosecond range. Because of the high occupancy expected, even in next year's LHC operation, it is significant that this technology has a completely scalable segmentation. This work is partly supported by a DOE Advanced Detector R&D grant, funded through Princeton University, which will also address the radiation damage issues. I will discuss also experience in timing measurement with undersampled waveforms using LHC data and outline a program to implement this technology in CMS/TOTEM.
