    "abstract": "The TOTEM collaboration has developed and tested the first prototype of its\nRoman Pots to be operated in the LHC. TOTEM Roman Pots contain stacks of 10\nsilicon detectors with strips oriented in two orthogonal directions. To measure\nproton scattering angles of a few microradians, the detectors will approach the\nbeam centre to a distance of 10 sigma + 0.5 mm (= 1.3 mm). Dead space near the\ndetector edge is minimised by using two novel \"edgeless\" detector technologies.\nThe silicon detectors are used both for precise track reconstruction and for\ntriggering. The first full-sized prototypes of both detector technologies as\nwell as their read-out electronics have been developed, built and operated. The\ntests took place first in a fixed-target muon beam at CERN\u0027s SPS, and then in\nthe proton beam-line of the SPS accelerator ring. We present the test beam\nresults demonstrating the successful functionality of the system despite slight\ntechnical shortcomings to be improved in the near future.",
