Reference

¶

The Reference module stores information about reference signal profiles and features.

References useful for analysis, so that we can measure deviation of signals.
References change over time, so we need to keep track of the changes.

1. Get Reference Quench Heater Discharge Timestamp¶

In [37]:

from lhcsmapi.reference.Reference import Reference

Reference.get_quench_heater_reference_discharge('RQ', '16L2')

Out[37]:

1417079205409000000

2. Get Reference Power Converter Timestamp¶

In [38]:

from lhcsmapi.reference.Reference import Reference

Reference.get_power_converter_reference_fpa('RQ', 'RQD.A12', 'fgcPm')

Out[38]:

'2018-03-18 11:58:33.600'

3. Get Reference Energy Extraction Timestamp¶

In [39]:

from lhcsmapi.reference.Reference import Reference

Reference.get_power_converter_reference_fpa('RQ', 'RQD.A12', 'eePm')

Out[39]:

'2018-03-18 11:58:33.675'

4. Get Reference Energy Extraction Parameters¶

In [41]:

from lhcsmapi.reference.Reference import Reference

Reference.get_energy_extraction_reference_parameters('RB', '2018-03-18 11:58:33.675')

Out[41]:

	min	max

tau_u_dump_res_1	110.0000	130.0000
tau_u_dump_res_2	110.0000	130.0000

In [42]:

from lhcsmapi.reference.Reference import Reference

Reference.get_energy_extraction_reference_parameters('RQ', '2018-03-18 11:58:33.675')

Out[42]:

	min	max
R_1	0.005	0.010
