List of all members.

Public Types

enum  BiasSetting { Slow = 0, Medium = 1, Fast = 2 }

Static Public Member Functions

static double delay (double fC, BiasSetting bias=Medium)
 Returns the amount (ns) by which a pulse of the given number of fC will be delayed by the timeslew effect, for the specified bias setting.

Detailed Description

copy from HCAL (author: J.

Mans)

Provides pulse delay as a function of amplitude for three choices of QIE bias setting. The "Medium" setting is used in HB and HE, while the "Slow" (and lower noise) setting is used in HO. All data taken from bench measurements of the QIE and plotted in Physics TDR Vol 1.

Not to be used for HF at this time (unlikely to have much effect, however)
