Absolute phase in a field map

[wtam]

Colleagues,

How can I obtain the "abs phase" at a certain location within a field map? I have tried a "marker" and short "drift" together with "shift_in_field_map" but it did not work. Any idea? Thanks!

Best regards,
Wai-Ming

Dear Wai-Ming,

Code: Select all

DIAG_SIZE 1
SHIFT_IN_FIELD_MAP 100
FIELD_MAP 70 480 0 40 9.174 0 0 0 qpole480_lme_25_01_07b

In this exemple, the diagnostic is located 100 mm inside field_map element and opening ENV_diag1.dat file I get the abs phase using beam parameters from the line "Positions (cm,cm,deg,MeV) : ...."

Regards,

Didier
