Data Support Lab

About the Laboratory

Data Support Laboratory (DSL) at Inter-University Accelerator Centre provides support to users for Data Acquisition and NIM electronics set up at Data Room. The lab has got a pool of NIM and CAMAC resources that can be issued to users for setting up the experiments.

DATA SUPPORT LAB (Next-gen Instrumentation & Acquisition Systems )

The data acquisition group NIAS-DSL caters to the DAQ needs of the nuclear and partical physics experiment setups @ IUAC. Mandate of the group is to design, develop and maintain the DAQ systems at IUAC. The indigenous development reduces the cost & import of modules to support the Make in India campaign in IUAC.

The group maintains both VME and CAMAC based DAQ setups @IUAC along with in-house developed GPL based softwares like MARS, CANDLE, BPA and MAPS. Over the years the group has developed, lots of software and hardware related to data acquisition and control system applications.

ROSE-MARS based VME DAQ at IUAC

Recently a VME crate Controller ROSE and an Event identifier module VGEM along with its software MARS (Multi-parameter Acquisition with Root based Storage) has been developed to cater the need of Data Acquisition at IUAC. The crate controller ROSE is used in IUACs accelerator control systems also.

LPCC based CAMAC DAQ at IUAC

A CAMAC crate controller LPCC, a 14 bit resolution ADC AD814 and an event identifier module GEM was developed earlier for CAMAC based DAQ systems at IUAC. The software CANDLE was developed for CAMAC based DAQs, which is a GUI cum collection and analysis engine, developed over years to its full strength for data analysis capabilities etc. Initially it was made for 32 bit systems later upgraded for upcoming 64 bit computers.
