What can we learn about MIPs from DCLINC ?

• in Rev. 172 two FF measurements in closed cal

n:= mean number of MIP tracks/cm2 sec

x:= mean number of columns with MIP events per MIP track

• DCLINC/cm2·sec = n · (x + 2·MIPSEL) (1)

MIPSEL 2 1

DCLINC/20 frames 157 111

DCLINC/cm2 sec 13.00 9.19

using (1):

n (x + 4 ) = 13.00

n (x + 2) = 9.19

n = 1.9 MIP tracks/cm2·sec

average width x = 2.8 columns
