NAME

Physics::UEMColumn::MagneticLens - A class representing a magnetic lens in a UEM system

SYNOPSIS

 use Physics::UEMColumn alias => ':standard';
 my $lens = MagneticLens->new(
   location => $position . 'cm',
   length   => $length . 'cm',
   strength => $strength,
 );

DESCRIPTION

Physics::UEMColumn::MagneticLens is a class representing a magnetic lens in a UEM system. It is a subclass of Physics::UEMColumn::Element and inherits its attributes and methods. Additionally it provides:

ATTRIBUTES

stength

Quantifies the strength of the magnetic lens. While this number is conceptually analytical, in practice this number is very hard to determine other than by comparison to lens in question. With this in mind, no unit is used on this attribute.

order

The super-Gaussian order exp( - $x ** ( 2 * $order ) ) determining the shape of the lens. Default is 1 (a Gaussian).

METHODS

effect

Returns a hash reference of effect subroutine references (M_t). See "METHODS" in Physics::UEMColumn::Element for more.
