“…Signals from this detector were processed in preamplifiers, shaping amplifiers, and digitized in VME TDCs and ADCs. Data was analyzed offline using the software GO4 [11]. Note that the TASISpec setup did not include any veto detector for impinging ions like, for example, a multi-wire proportional counter.…”

The gas-filled separator TASCA will be employed, sending the residues towards the multi-coincidence detector setup TASISpec. Two ionoptical modes relying on differing magnetic polarities of the quadrupole magnets can be used at TASCA. New simulations and experimental tests of transmission and background suppression for these two focusing modes into TASISpec are presented.

he LHC is at present the world's largest and highest-energy particle accelerator, hosted at CERN, the European particle physics laboratory near Geneva. The TOTEM experiment was designed to measure the total pp cross section and to study elastic scattering and diffractive dissociation at LHC. The protons that underwent elastic interaction are lightly deflected and, to detect them, TOTEM has installed silicon strip detectors at more than 200 m from the interaction point that can transversally approach the beam down to few millimetres, thanks to a movable piece of the vacuum chamber called Roman Pot.During the first period of operation of the LHC, the TOTEM run campaigns were accomplished during low luminosity dedicated data taking. However, to allow the investigation of rare phenomena, an upgrade program has been proposed by the TOTEM Collaboration, to make possible the data taking at higher luminosities. In particular, a cornerstone of the upgrade program is the inclusion of a fast timing detector in the experimental apparatus to improve the capability of the apparatus to work in high pileup conditions.The main topic of this thesis is the design and the characterization of a fast timing detector for high energy protons. After a survey of the most promising sensor technologies available for fast timing measurements, it was proved, thanks to an extensive campaign of tests using particle beams, that the needed resolution, below 100 ps, was achievable using diamond sensors. In particular, different approaches for the front-end electronics were investigated: some commercially available amplifiers and the timing detector designed by the HADES Collaboration were characterized.Then, a diamond detector, fully compliant with the TOTEM requirements, was designed, tested and prepared for the installation in the RP system. In parallel, 13Introduction other solutions were investigated, such as 3D graphitized diamond sensors and an amplitude dependent amplifier, designed to increase the signal to noise ratio: the gain of the amplifier is small for low amplitude input (noise) and higher in presence of a signal.In particular, the first chapter describes the TOTEM experiment and the main physics results obtained during the first run of the LHC. Then, the physics motivation and the technological challenges of the consolidation and upgrade programs are discussed. Particular attention is given to the impedance optimization of the Roman Pot, described in the second chapter. In fact, the Roman Pot creates a cavity inside the primary vacuum that can resonate at the passage of the beam.This resonance can introduce instabilities in the beam and can, in the worst cases, damage the detector because of the excessive heat generated. The Roman Pot has been optimized in this sense and two new shapes have been designed and realized and, only thanks to this optimization, the Roman Pot can be safely inserted at few millimetres from the beam even at the highest intensities foreseen for the LHC.In the third chapter, the properties of diamond are dis...

The Data Acquisition Backbone Core (DABC) is a new GSI software framework to run a data acquisition with distributed event building on high performance Linux clusters. Experiment specific front-end electronics is to be integrated to the software by means of hardware interface plug-ins like Device and Transport classes. DABC offers elaborate mechanisms for multiprocessing, buffer management, and dataflow throttling. These are transparently available for all implemented plug-ins. Device plug-ins can link a DABC node to remote readout hardware via network connections like Ethernet. Other Device plug-ins can communicate on the Linux device driver level with custom boards directly inserted at the node.Besides delivering the data input, a DABC Device can also provide control access to the connected hardware. This functionality can be used for setting up, or monitoring the front-ends from the application via DABC parameters and commands. An implementation example is a multipurpose PCI Express Optical Receiver (PEXOR) board developed at GSI. This board features an FPGA and 4 optical links and may be used for various front-ends, depending on the FPGA programming. A kernel driver and the DABC Device plug-in for this board have been developedand tested. They are described here with some performance benchmark results.As another example, DABC is applied for data taking during test beam times of the Compressed Baryonic Matter (CBM) experiment from 2008 to 2010. Here the front-end readout controller boards (ROC) were integrated to the DABC hardware interface, both for a UDP based Ethernet protocol, and for optical connections to a custom PCIe board.
