Introduction Our system SunSort & ROOT Other supported electronics MIDAS VME DAQ Laboratory for Nuclear Physics, RBI L. Prepolec November 5, 2011 L. Prepolec MIDAS VME DAQ Conclusion Introduction Our system SunSort & ROOT Overview 1 Introduction 2 Our system Hardware Software 3 SunSort & ROOT 4 Other supported electronics 5 Conclusion L. Prepolec MIDAS VME DAQ Other supported electronics Conclusion Introduction Our system SunSort & ROOT Other supported electronics Important The main goal of this presentation is to describe the DAQ currently used in the LNP at RBI. The author’s knowledge of MIDAS is limited to experience with the existing system. L. Prepolec MIDAS VME DAQ Conclusion Introduction Our system SunSort & ROOT Other supported electronics Conclusion Introduction background: nuclear structure group exotic nuclei nuclear astrophysics large–area segmented silicon detectors (hundreds of channels) University of Birmingham NP group (M. Freer) acquire compatible system (N. Soić) took a decade completed two years ago, including DAQ L. Prepolec MIDAS VME DAQ Introduction Our system SunSort & ROOT Other supported electronics Hardware Our system based on the MIDAS L. Prepolec MIDAS VME DAQ (http://npg.dl.ac.uk/MIDAS) Conclusion Introduction Our system SunSort & ROOT Other supported electronics Hardware Our system based on the MIDAS hardware components (http://npg.dl.ac.uk/MIDAS) Wiener UEP 6021 VME430 6U crate (21 slot) Motorola MVME 2434 VME processor module SAC (Silena 9418 Acquisition Control module) SlLENA 9418/6-V 32 ch. 12 bit ADC Sun Fire x4100 M2, OS Solaris 10 L.

Prepolec MIDAS VME DAQ Conclusion Introduction Our system SunSort & ROOT Other supported electronics Hardware Wiener UEP 6021 VME430 6U crate L. Prepolec MIDAS VME DAQ Conclusion Introduction Our system SunSort & ROOT Other supported electronics Hardware Motorla MVME 2434 VME processor module 350 MHz MPC750 (big endian!) 256MB ECC SDRAM 10/100Mb/s Ethernet interface debugging serial port in our case runs MIDAS on LynxOS L. Prepolec MIDAS VME DAQ Conclusion Introduction Our system SunSort & ROOT Other supported electronics Hardware SAC (Silena 9418 Acquisition Control module) ALTERA MAX CPLD (Complex Programmable Logic Device) triggering ADCs through front panel connection support for both Silena 9418 and CAEN V785 32 ch. 12 bit ADCs including mixed configuration common trigger for other units (TDCs, QDC, etc.) L. Prepolec MIDAS VME DAQ Conclusion Introduction Our system SunSort & ROOT Other supported electronics Hardware Silena 9418/6-V ADC 32 channel peak sensing ADC multi-strecher configuration + high speed conversion module two “piggy-back” board on the module 12 bit resolution, 10 µs conversion time individual rise time protection and low level thresholds dynamic range 8V; sliding scale L. Prepolec MIDAS VME DAQ Conclusion Introduction Our system SunSort & ROOT Other supported electronics Hardware Sun Fire x4100 M2 fairly standard 1U server 2x Dual-Core AMD Opteron Processor 2218 2.6 GHz 8 GB DDR2 ECC RAM 2x 146 GB 10000 rpm SAS HDD in HW RAID 1 4x Gb ethernet redundant power supply, remote mgt. Solaris 10 certified and preinstalled L. Prepolec MIDAS VME DAQ Conclusion Introduction Our system SunSort & ROOT Other supported electronics Conclusion Software MIDAS made by Daresbury lab, written in TCL (script language) UoB: Sun Workstations (SPARC), today laptops with Open Solaris (not Linux because of SunSort) MIDAS in general: Solaris (both SPARC and x86), Linux, Windows) Motorola VME processor card (MVME 2400 or 5500) + SAC L. Prepolec MIDAS VME DAQ Introduction Our system SunSort & ROOT Other supported electronics Conclusion Software MIDAS boot VME CPU from computer via TFTP MVME 2400 series: LynxOS starts MIDAS NFS connection to Tape Server on computer MIDAS: Tape Server Message Logger Experiment Control Online plots Amp control L. Prepolec MIDAS VME DAQ SunSort: written by and for CHARISSA colaboration graphical user interface works in CDE - serious constraint not very user friendly very fast, has all the data formats we need Introduction Our system SunSort & ROOT Other supported electronics Data format partially documented byte swapping hex editor, existing code + some time gained full understanding of the format conversion to ROOT SunSort & ROOT “&” is on purpose speed and reliability vs. “mainstream” data analysis tool ROOT slow but should pay off in the long run maintainance of SunSort a bit problematic use both L. Prepolec MIDAS VME DAQ Conclusion Introduction Our system SunSort & ROOT Other supported electronics As stated in online documentation (VME hardware only) ADC TDC QDC digital discr. multiplex. L.
