Diamonds as timing detectors for MIPS: The HADES proton-beam monitor and start detectors

نویسنده

  • W. Koenig
چکیده

Diamond detectors are well known for their radiation hardness and high drift speeds of both electron and holes making them ideal as start detectors placed in the beam. However, due to the large effective energy needed to create electron hole pairs (13 eV) the charge created by minimum ionizing particles (MIPS) traversing the diamond is marginal (8000 pairs for a 300 μm thick diamond) [1]. In the following a dedicated, low noise readout scheme is described as well as its application as a start detector for protons in the HADES experiment.

Advances in gaseous time-of-flight detectors

Timing Resistive Plate Chambers (RPCs) are planar gaseous detectors made with a combination of metallic and resistive electrodes, delivering time resolutions around 50 ps σ and efficiency up to 99% for MIPs. In this work we describe the development and test of an electrically shielded timing RPC array for crosstalk-free time measurements in high granularity time-of-fight (TOF) systems, as the I...

Development of Single-Crystal CVD-Diamond Detectors

Single-Crystal CVD-Diamond Detectors (SC-DD) of ~ 300μm thickness have been tested in Cave A with proton beams of Ep > 1AGeV as start detectors for minimum ionizing particles. Fast charge-sensitive amplifiers developed at GSI and Bucharest were used. At particle rates up to 1MHz, stable operation and detection efficiency of ~100% are observed. The measured time resolution of σ ≥ 330ps is not sa...

Dosimetric characteristics of active solid state detectors in a 60 MeV proton radiotherapy beam

The solid state active detectors, widely used for conventional radiotherapy, such as diamond detectors (DD) and diodes may be attractive tools also in dosimetry of therapeutic proton beams. Diodes are broadly applied in oncology clinics and routinely used for in-vivo dosimetry [1, 8]. These real-time detectors are rugged, relatively inexpensive and provide on-line readings, what allows for quic...

Preliminary Characterization Tests of Detectors of on-Line Monitor Systems of the Italian National Center of Oncological Hadron-Therapy (CNAO)

Introduction Hadron-therapy is an effective technique used to treat tumors that are located between or nearby vital organs. The Italian National Center of Oncological Hadron-therapy (CNAO) has been realized as the first facility in Italy to treat very difficult tumors with protons and Carbon ions. The on-line monitor system for CNAO has been developed by the Department of Physics of the Univers...
