Database entry of irradiation data
Database entry of irradiation data

  • PROBLEMS

  • New form of DB data

  • One set of data may de-qualify whole batch of sensors  composite of composite action: NEW

  • Tests are done on teststructures  TS is NOT a database object 

    • Even worse: diodes and minisensors on TS 

    • how to name? WHERE to register?

  •  in addition there will be modules to be irradiated.

  • FACT: The PQC centers will face the same problem


Steps to go and possible solution
Steps to go, and possible solution

  • The composite of composite action has to be introduced in the DB scheme

  • IQC and also PQC tables could be inserted in the QTC existing DB objects

    • Addition of new tables

    • Optional, since only a fraction will be irradiated

  • M200 and pre-series is approaching fast!

    • Many pre-series sensors are delivered and tested


Preliminary irrad tables already exist in xml
Preliminary Irrad tables already exist in XML

  • Tables are done and already underwent one iteration between Karlsruhe and Louvain

  • We will have 3 simple tables:

    • diodeminisensorsensor

    • Tables show the results from the agreed measurements:

      ONE Ramp, values @Vbias=400V, difference of values before and after irradiation @Vbias=400V


Db content for sensor minissensor
DB content (for sensor & minissensor)

  • ENV: Date,Time;Irrad_Date;Comment;Humidity,Temp

    Duration; operator; location; status

  • GLOBAL: I_TOT, V_dep; C_TOT; alpha (before and after irrad)

  • IRRAD-SPECS: fluence(p,n); dose(p,n); energy(p,n)

  • STRIP-PARAMETERS: X* [Rpoly;Cint;Ileak;Rint (CAC optional)]@Vstandard =400V

    Delta of all strip parameters before and after irrad

  • Raw Data: IV,CV, ONE RAMP {Rpoly;Cint;Ileak;Rint (CAC optional)} vs. Voltage


Tables for diode
Tables for diode

Tables for sensors and minisensors are similar but more extensive.

Pending actions
Pending Actions

  • Agreement how to label tables for diode, sensor, minisensor!?!

    Is the diode, the irrad. Sensor and the minisensor a component of the sensor (same ID)? YES!!!!!!

    Are they seperate objects; where will they be registered?

    NO!!!!!!!!!

  • @DB people implementation of the „composite of composites“

  • Implementation of the agreed! Tables into the DB (discussion underway)

  • Labview vi for the XML output (will be done by KA)

  • FINAL OK: MANUALLY (proposal from software)
