“…The drift induces a current pulse at the electrodes. The induced initial current can be calculated by the Shockley-Ramo Theorem [12], [13] for a uniform constant field between the two electrodes as (4) where denotes the total ionization charge, the drift velocity, and the gap between the electrodes, which is equal to the thickness of the detector. The total initial ionization charge is which yields an incident detector current of A (5) which is independent of the detector thickness and the chargecollection distance .…”

Abstract-This paper presents the design and test results of a charged-particle solid-state detector with ultrafast signal response based on polycrystalline chemical-vapor-deposition (pCVD) diamond as active detector material and a high-bandwidth RF amplifier. We tested the detector at the Indiana University Cyclotron Facility Bloomington, IN, in a proton beam with a kinetic energy ranging from 55 to 200 MeV. The detector signals showed an average pulsewidth of 1.38 ns, which enables single-particle counting at instantaneous rates approaching the gigahertz range. The detector operated with a signal-to-noise ratio of 7 : 1 for 200-MeV protons and a single-particle detection efficiency up to 99%.

“…Incomplete charge collection is worse for the Si-ion excitation as compared to the He-ion excitation because of the higher excitation density expected in Si-ion excitation leading to a larger plasma effect in the charge collection process. Furthermore, in order for such large incomplete charge collection to occur, the carrier trapping/recombination in the bulk of the detector via defects must be the dominant process responsible for the decay of the free carriers as compared to the loss of the carriers at the metal/diamond interface, especially with the electric field expected to be depressed due to plasma screening [4]. This is consistent with the fact that diamond is known to contain a variety of structural defects and impurities, especially large quantities of nitrogen acting as deep donors [9].…”

Sub-Nanosecond Detection of Heavy Ions Using Single-Crystal, Natural Type IIA Diamond

The sub-nanosecond electrical transients induced by 5-MeV He+ and 10-MeV Si 3 + ions have been measured in single-crystal, natural type Ila diamonds. The detectors were fabricated into conductivity modulated devices and were incorporated into 50-f4 high bandwidth transmission line structures. The electrical signals were recorded with a system based on a 70 GHz random sampling oscilloscope with the total recording rise time of 18.6 ±:0.6 ps.Signal rise times are less than 70 ps and fall times are less than 200 ps for electric fields in the range 3.8x10 4 -lxl0 5 V/cm. The plasma time appears to play a key role in defining the initial stages of the charge transport because signal rise times are much greater than the recording system rise time, especially with the Si-ion excitation. Furthermore, incomplete charge collection is quite severe even at the highest applied electric fields due to the dominance of carrier trapping/recombination at the defect sites.

In this paper, we present experimental and numerical studies of the calibration of lowmultiplicity electron source using signals from electrons incident on a diamond detector. The experiments were performed at the newly commissioned versatile LEETECH platform at the PHIL photoinjector facility at LAL. We show that with a single crystal CVD diamonds of 500 micrometers thickness, the energy losses from the first three electrons of 2.5-3 MeV are clearly resolved. The described technique can be used as a complementary approach for calibration of diamond detectors as well as for diagnostics of accelerated beam halos in a regime down to a few particles.
