Constants Module

Import these constants from spyral_utils.constants

Module of some common constants aliased from scipy to avoid long key strings and with units most relevant to AT-TPC data.

Attributes:

Name Type Description

converts u to MeV/c^2 (MeV/c^2 / u)

ELECTRON_MASS_U float

mass of an electron in amu (amu)

MEV_2_JOULE float

Convert MeV/c^2 to J (J/MeV/c^2)

MEV_2_KG float

Convert MeV/c^2 to kg (kg/MeV/c^2)

ROOM_TEMPERATURE float

Room temperature in K (K)

GAS_CONSTANT float

The gas constant (cm^3 Torr / (K mol))

QBRHO_2_P float

Constant used to convert magnetic rigidity times charge (unitless) to momentum (MeV/c / (T*m))

C float

speed of light (m/s)
