RAMPP

A momentum-ramping element that changes the central momentum according to an SDDS- format file of the momentum factor vs time in seconds.
Parallel capable? : yes

Parameter Name	Units	Type	Default	Description
WAVEFORM		STRING	NULL	$<$filename$>$=$<$x$>$+$<$y$>$ form specification of input file giving momentum factor vs time
GROUP		string	NULL	Optionally used to assign an element to a group, with a user-defined name. Group names will appear in the parameter output file in the column ElementGroup

Explanation of $<$filename$>$=$<$x$>$+$<$y$>$ format: Several elements in elegant make use of data from external files to provide input waveforms. The external files are SDDS files, which may have many columns. In order to provide a convenient way to specify both the filename and the columns to use, we frequently employ $<$filename$>$=$<$x$>$+$<$y$>$ format for the parameter value. For example, if the parameter value is waveform.sdds=t+A, then it means that columns t and A will be taken from file waveform.sdds. The first column is always the independent variable (e.g., time, position, or frequency), while the second column is the dependent quantity.
