Print Machine Settings Overview

Prints an overview over the machine settings at a provided given time, or the current settings if no time is given. If an output path is given, all info will be written into tfs files, otherwise a summary is logged into console.

Knob values can be extracted and the knob definition gathered. For brevity reasons, this data is not logged into the summary in the console. If a start time is given, the trim history for the given knobs can be written out as well. This data is also not logged.

Can be run from command line, parameters as given in pylhc.machine_settings_info.get_info(). All gathered data is returned, if this function is called from python.

 usage: machine_settings_info.py [-h] [--time TIME] [--start_time START_TIME]
                                 [--knobs KNOBS [KNOBS ...]] [--accel ACCEL]
                                 [--beamprocess BEAMPROCESS] [--output_dir OUTPUT_DIR]
                                 [--knob_definitions] [--source SOURCE] [--log]

optional arguments:
-h, --help            show this help message and exit
--time TIME           UTC Time as 'Y-m-d H:M:S.f' or ISO format or AccDatetime object.
                      Acts as point in time or end time (if ``start_time`` is given).
--start_time START_TIME
                      UTC Time as 'Y-m-d H:M:S.f' or ISO format or AccDatetime object.
                      Defines the beginning of the time-range.
--knobs KNOBS [KNOBS ...]
                      List of knobnames. If `None` (or omitted) no knobs will be extracted.
                      If it is just the string ``'all'``, all knobs will be extracted
                      (can be slow). Use the string ``'default'`` for pre-defined knobs
                      of interest.
--accel ACCEL         Accelerator name.
--beamprocess BEAMPROCESS
                      Manual override for the Beamprocess
                      (otherwise taken at the given ``time``)
--output_dir OUTPUT_DIR
                      Output directory.
--knob_definitions    Set to extract knob definitions.
--source SOURCE       Source to extract data from.
--log                 Write summary into log (automatically done if no output path is given).

class pylhc.machine_settings_info.AccDatetimeOrStr(value)[source]: A class that accepts AccDateTime and strings.

pylhc.machine_settings_info.get_info(opt) → Dict[str, object][source]

Get info about Beamprocess, Optics and Knobs at given time.

Keyword Args:

--Optional--

accel (str):

Accelerator name.

default: lhc

beamprocess (str):

Manual override for the Beamprocess (otherwise taken at the given time)

default: None

knob_definitions:

Set to extract knob definitions.

action: store_true

knobs (str):

List of knobnames. If None (or omitted) no knobs will be extracted. If it is just the string 'all', all knobs will be extracted (can be slow). Use the string 'default' for pre-defined knobs of interest. If this is called from python, the strings need to be put as single items into a list.

default: None

log:

Write summary into log (automatically done if no output path is given).

action: store_true

output_dir (PathOrStr):

Output directory.

default: None

source (str):

Source to extract data from.

default: nxcals

start_time (AccDatetime, str):

UTC Time as ‘Y-m-d H:M:S.f’ format or AccDatetime object. Defines the beginning of the time-range.

default: None

time (AccDatetime, str):

UTC Time as ‘Y-m-d H:M:S.f’ format or AccDatetime object. Acts as point in time or end time (if start_time is given).

default: None

Returns:
dict: Dictionary containing the given time and start_time, the extracted beamprocess-info and optics-info, the trim_histories and current (i.e. at given time) trims and the knob_definitions, if extracted.

pylhc.machine_settings_info.log_summary(acc_time: AccDatetime, bp_info: DotDict, optics_info: DotDict = None, trims: Dict[str, float] = None)[source]

Log the summary.

Parameters:

acc_time (AccDatetime) -- User given Time
bp_info (DotDict) -- BeamProcess Info Dictionary
optics_info (DotDict) -- Optics Info Dictionary
trims (dict) -- Trims key-value dictionary

pylhc.machine_settings_info.write_knob_defitions(output_path: Path, definitions: dict)[source]: Write Knob definitions into a tfs file.

pylhc.machine_settings_info.write_summary(output_path: Path, accel: str, acc_time: AccDatetime, bp_info: DotDict, optics_info: DotDict = None, trims: Dict[str, float] = None)[source]

Write summary into a tfs file.

Parameters:

output_path (Path) -- Folder to write output file into
accel (str) -- Name of the accelerator
acc_time (AccDatetime) -- User given Time
bp_info (DotDict) -- BeamProcess Info Dictionary
optics_info (DotDict) -- Optics Info Dictionary
trims (dict) -- Trims key-value dictionary

pylhc.machine_settings_info.write_trim_histories(output_path: Path, trim_histories: Dict[str, namedtuple], accel: str, acc_time: AccDatetime = None, acc_start_time: AccDatetime = None, bp_info: DotDict = None, optics_info: DotDict = None)[source]

Write the trim histories into tfs files. There are two time columns, one with timestamps as they are usually easier to handle and one with the UTC-string, as they are more human-readable.

Parameters:

output_path (Path) -- Folder to write output file into
trim_histories (dict) -- trims histories as extracted via LSA.get_trim_history()
accel (str) -- Name of the accelerator
acc_time (AccDatetime) -- User given (End)Time
acc_start_time (AccDatetime) -- User given Start Time
bp_info (DotDict) -- BeamProcess Info Dictionary
optics_info (DotDict) -- Optics Info Dictionary

BSRT logger

Script used during Run II to log detailed BSRT data and save it for later analysis. Data from the BSRT for each timestep is put in a dictionary and append to a list. The list is then saved to disk through pickling. Proper testing requires communication with FESA s class, possible only from the Technical Network.
