Detailed Description

Various constraints for CDC wires (w.r.t. layers)

Definition at line 363 of file constraints.py.

Constructor & Destructor Documentation

◆ init()

def __init__	(	self,
		filename = `'cdc-wire-constraints.txt'`,
		layers = `None`,
		layer_rigid = `True`,
		layer_radius = `False`,
		cdc_radius = `False`
	)

Initialize constraint

Parameters
----------
filename : str
  Can override the default file name
layers : list (int)
  List of layer numbers for which to generate the constraints (default is 0..55)
layer_rigid : bool
  6 constraints - fix sum of shifts of wire ends in x/y/rotation at fwd/bwd end-plate
layer_radius : bool
  2 constraints to fix average change of layer radius (wires in layer moving away from origin)
cdc_radius : bool
  1 constraint - fix average change in CDC radius from all wires

Definition at line 380 of file constraints.py.

Member Function Documentation

◆ configure_collector()

def configure_collector	(	self,
		collector
	)

Enables wire-by-wire derivatives in collector

Reimplemented from Constraints.

Definition at line 415 of file constraints.py.

◆ generate()

def generate ( self )

Generate constraints

Reimplemented from Constraints.

Definition at line 429 of file constraints.py.

◆ get_label()

def get_label	(	self,
		layer,
		wire,
		parameter
	)

Return GlobalLabel for wire parameter

Definition at line 421 of file constraints.py.

Member Data Documentation

◆ filename

filename

inherited

File name.

filename : str
  Desired filename for the constraint file

Definition at line 67 of file constraints.py.

◆ layer_rigid

layer_rigid

6 x 56 (6/layer) constraints.

Sum(dX_B/dY_B/drot_B/dX_FB/dY_FB/drot_FB)=0 for all wires in each layer -> removes the basic unconstrained DoF when aligning wires and layers simultaneously. Average shift and rotation of wires in layer (at each end-plate) = 0. -> coherent movements of wires absorbed in layer parameters

Definition at line 407 of file constraints.py.

◆ layers

layers

List of layers for whose wires to generate the constraints.

None = all layers

Definition at line 402 of file constraints.py.

◆ wires_in_layer
