1. Online Calibration Online calibration: validation: L3fCalCalibTool –
produces , for pedestals
validation:
check of pedestal values
applies values and check of occupancy
shift monitoring:
occupancy checks during data taking
Calibration Manager
Online database:
– pedestal value tables
extraction tables:
downloaded in ADC’s
bad cell lists

2. Online calibration db design
mapping not very useful
no bad cell bookkeeping
only final output of gain calibration
mean and sigma values for both gain paths in 1 table
non-intuitional numbering scheme

3. New Proposed design

4. Continuous Channel Numbering?
CHANNEL_ID DEPTH_ID PDEPTH_ID TOWER_ID PTOWER_ID
jump in numbering:
reason vanished as extraction tables have to be created

5. Continuous Numbering
channel_id = depth+12*(tower+4*(bls+8*(adc+12*(crate))))
depth=[0-11]
tower=[0-3]
bls=[0-7]
adc=[0-11]
crate[0-11]
cal_address is based on a similar channel_id
easy to interface in online/offline
no additional mapping tables needed

6. Specifications bit coding of crates in calibration run
peds, gain, time
0: non valid; 1: valid
Reason of badness:
sigma, sigma x1,sigma x8
ped, ped x1, ped x8
occupancy

7. Current Offline Db
can be easily matched with online database to allow for simple copy and expansion from online tables

8. Steps Online database verification of proposed online design
matching with offline design
population of new online tables with values from pre-shutdown data (including clean up)
population of offline tables, test of server and client code
L3fCalCalibTool
gain calibration debugging
Validation
