Overview

What’s included in CondDb. Alignment Readout Slow/fast control calibration

Ex/DetCondExample/v7r7 (sort of old ver.) Example package for LHCb CondDb.

Ex/DetCondExample/v11r2 (recent ver.) A little bit reorganized structure.

Xml-based Data base

CondDb uses xml files. Examples are shown next slides

Xml string can be put to actual Db server via COOL package.

What if we need to access Heidi’s hardware Db from Gaudi framework? It’s possible to convert conventional Db to Xml Db.

Pmt calibration, … Is it safe to have mutiple Dbs?

Running test program

I could run a test program that reads file-based Db and prints out the values.

I couldn’t test example that works with actual Db.

The package includes: Algorithm that fills xml to Db. Algorithm that loads xml from Db. A script that creates Db. A script that copies xml to Db.

What we’ll need

Alignment data It should be given to reconstruction package(i.e.

tracker finder, track fitter) and calibration package.DAQ Conditions/calibration

It should be given to Sergei’s Readout packages.Cosmic calibration

Need calibration package that calculate calibration date.

The calibration output will be used to other packages.

Mapper software

Using root Read Leo’s manual scan data text file in new

Framework. Some of code is imported from old one. Plan to add a piece that handle binary data from real mapper

DAQ. What’s been done

Basic framework and data class Data is organized into tree structure, so easy to handle for

further complicated analysis Pedestal curve is fitted and pedestal shift is calculated. Transverse scan fit is progress.
