The WaveCatcher systems are a family of powerful and low cost digitizers. Their number of channels currently ranges between 2 and 64 (+8) channels.
They all make use of the SAMLONG analog memory chips which permit sampling the input signal between 400 MS/s and 3.2 GS/s over 12 bits and with a signal bandwidth of 500 MHz.
There are 4 different types of systems:
• 2-channel, USB-powered handy...
The Technological Unit of the Institute of Cosmos Science of the Universitat of Barcelona (ICCUB) is specialized in developing microelectronics for applications in which low noise and high bandwdith are key features. We currently have different test setups equipped with both 8 and 16 channel WaveCatchers, including ASICs' tests for the Cherenkov Telescope Array (CTA) and the LHCb projects, as...
The SuperNEMO experiment goal is to probe the nature of the neutrino through the neutrinoless double beta decay research. It uses the so-called tracko-calo technique which allows not only to measure the energy of particle traversing the detector but also to reconstruct their track, time of flight and full kinematic.
Specific boards using Wavecatcher architechture are used...
Within this work we shortly represent analysis software for WaveCatcher raw data treatment. The software is based on C++ and root libraries, bash is used to run analysis scrips.
Different modules are developed for binary/ASCII and/or measurements/rates/waveform treatment.
The analysis path have tree main steps :
1) Conversion of WaveCatcher raw data into the root format.
2.1) waveform analysis...
The possible use of bent crystals for beam-manipulation in particle accelerators is currently investigated by the UA9 collaboration at CERN. One application could be the upgrade of collimation system for hardron colliders such as LHC - with an improved cleaning efficiency of the beam halo and a reduced impedance of the machine.
Investigation of this channeling process close to a circulating...
We are developing a real-time monitoring system using a diamond-detector and a Wavecatcher to characterise the gamma source at ELI-NP, a new nuclear research facility in Romania. The main technological challenge is to obtain the necessary information from 32 consecutive pulses of gammas separated from one another by 16 ns. Two preliminary experiments have been performed at existing Compton...
Plastic scintillator detectors have been extensively used in particle physics experiments for decades.
In large-scale experiments, they are typically arranged as an array of staggered long bars covering a large surface and provide a fast trigger signal or particle identification.
This technology is proposed for the timing detector of the SHiP experiment at CERN SPS. Results of test-beams are...
Using a 16 channel 8Gs/s Sampic board, a study of the achieved time resolution limit is performed for a reference Low Gain Avalanche Diode Setup. Using constant fraction linear extrapolation, a 42 psec time resolution is achieved for a pair of identical sensors and without any single fitting technics. Calibration and trigger corrections are applied while comparison with a 20Gs/s oscilloscope...
It is often necessary to perform a full synchronisation of multiple digitizer boards. This talk will present the way to:
- distribute the same clock to the boards
- make simultaneous start of the acquisition
- distribute the trigger signal in triggered or trigger-less systems
- keep the events synchronized across the boards
A new generation of parasitic beam extraction of high energy particles from an accelerator is proposed in CRYSBEAM. Instead of massive magnetic kickers, bent thin crystals trapping particles within the crystal lattice planes are used. This type of beam manipulation opens new fields of investigation of fundamental interactions between particles and of coherent interactions between particles and...
In the framework of the development of a radiation protection detector, the Wavecatcher acquisition board was used as a portable system with a battery and a laptop. The oscilloscope, the scaler counter, and the waveform recording features were used.
The new Gamma Beam System (GBS), within the ELI‐NP project, under installation in Magurele (RO) by INFN, as part of EuroGammaS consortium, can provide gamma rays that open new possibilities for nuclear photonics and nuclear physics.
ELI‐GBS gamma rays are produced by Compton back‐scattering to get monochromaticity (0,1% bandwidth), high flux (1013 photon/s the highest in the world), tunable...

Two projects are under development. CaLIPSO project investigates the possibility to build the brain
and pre-clinical PET device with a high spatial resolution of the order of 1 mm3.
It uses an innovative...

Hadrontherapy can be defined as radiotherapy by means of proton or light ion beams. This alternative technique enables a highly localized dose deposition and better organ-at-risk...
ALTO is a wide field-of-view air shower array for very-high-energy (VHE) gamma-ray astronomy, proposed to be installed in the Southern Hemisphere at an altitude of ~ 5 km above sea level. The current project is an array of 1248 Detection Units (DU) distributed in 208 clusters of 6 DUs. A DU consists in 2 detectors separated by a concrete layer serving as electron/gamma shielding: above the...
