Revisione del layout e produzione della scheda elettronica per i sensori del rivelatore GBO per LUXE

Revision of the layout and production of the electronic card for the sensors of the GBO detector for LUXE

 

 


Schede HV_SWITCH BOX per Atlas - Front Panel

Schede HV_SWITCH BOX per Atlas - Rear panel

HV_SWITCH BOX per Atlas

 

The box allows you to switch a 1KV voltage on 4 outputs, through digital signals coming from the DB9 connector, or manually through 4 switches located on the rear panel.

The box was designed to interface with the Keithley 2400 Series Source Meters

input:

  • 1 x 1KV HV channel
  • 1 DB9 connector to digitally drive the outputs

output:

  • 4 x 1KV HV channels

 

 


Test di un nuovo batch di schede POLAR_FPGA per EEE

Testing a new batch of POLAR_FPGA boards for EEE

 

Low consumption board for the acquisition of pulse signals, for measuring times and pulse widths, coincidences and trigger generation

  • FPGA Cyclone V Intel (ex Altera)
  • 32 LVDS inputs
  • Interfaceable with GPS module and Raspberry PI
  • Connector for micro-SD memory and for two USB port modules
  • Power supply from 9 to 14V

2 PCB 4 Layers per due circuiti analogici ottimizzati per l’acquisizione di segnale provenienti dal rilevatore a scintillazione dell’esperimento FAMU

2 PCB 4 Layers for two analog circuits optimized for signal acquisition coming from the scintillation detector of the FAMU experiment

 

Each card features minimal distortion and gain uniformity across the sample interval. There is also a control on the supply voltage which is interrupted for values ​​greater than 5V.

Card with differential input:

  • Operational amplifier with high linearity in the ADL5565 band of interest;

Card with single input:

  • ADA4930 high linearity operational amplifier in the band of interest;

Both cards have a differential output and provide signals to an ADC for subsequent conversion to digital.
