Energy and Wavelength with bliss. Example xml file:

for tunable wavelength beamline:

<object class=”Energy”>: <object href=”/energy” role=”energy_motor”/> <object href=”/bliss” role=”bliss”/>

</object> The energy should have methods get_value, get_limits, get_state and move. If used, the controller should have method moveEnergy.

for fixed wavelength beamline:

<object class=”Energy”>: <read_only>True</read_only> <energy>12.8123</energy> or <object href=”/energy” role=”energy_motor”/>

The energy should have methods get_value and get_state </object>

Classes

Energy and Wavelength with bliss.

class mxcubecore.HardwareObjects.BlissEnergy.BlissEnergy(name)[source]#

Energy and Wavelength with bliss.

get_limits()[source]#: Return energy low and high limits. :returns: two floats tuple (low limit, high limit) [keV]. :rtype: (tuple)

get_value()[source]#: Read the energy. :returns: Energy [keV] :rtype: (float)

set_value(value, timeout=0)[source]#

Move energy to absolute position. Wait the move to finish. :param value: target value. :type value: float :param timeout: optional - timeout [s],

If timeout == 0: return at once and do not wait if timeout is None: wait forever.

Raises:: ValueError – Value not valid or attemp to set write only actuator.
