Detailed Description

Class for emittance conversion from (r,r') to (x,x').

Constructor & Destructor Documentation

◆ EmittanceConv()

EmittanceConv::EmittanceConv	(	uint32_t	n,
		uint32_t	m,
		const std::vector< double > &	r,
		const std::vector< double > &	rp,
		const std::vector< double > &	ap,
		const std::vector< double > &	I,
		uint32_t	rotn = `100`,
		double	xmin = `std::numeric_limits<double>::quiet_NaN()`,
		double	xpmin = `std::numeric_limits<double>::quiet_NaN()`,
		double	xmax = `std::numeric_limits<double>::quiet_NaN()`,
		double	xpmax = `std::numeric_limits<double>::quiet_NaN()`
	)

Constructor for (x,x') emittance data and statistics from (r,r') data.

EmittanceConv class reads particle diagnostic data arrays for r (radius), rp (radial angle), ap (skew angle) and I (current) and builds (x,x') data in a grid array of size n by m. Here the skew angle is $r\omega/v_z$ , where is the velocity to the direction of beam propagation. The conversion is done by rotating each trajectory diagnostic point around the axis in rotn steps (defaults to 100). The output grid size can be forced by setting (xmin,xpmin,xmax,xpmax) variables, otherwise the grid is autotomatically sized to fit all data.

The emittance statistics is built using original data and not the gridded data for maximized precision.
