# The `NPI_tof_theta_monitor` Component

Cylindrical (2pi) PSD Time-of-flight monitor.

## Identification

- Site:
- Author: Kim Lefmann
- Origin: Risoe
- Date: October 2000

## Description

    Derived from TOF_cylPSD_monitor.
    Code is extended by the option allowing to define range of scattering angles, therefore creating only a part of the cylinder surface.
    The plot is transposed when compared to TOF_cylPSD_monitor: scattering angles are on the horizontal axis.

    Example:	TOF_cylPSD_monitor_NPI(nt = 1024, nphi = 960, filename = "Output.dat",
    radius = 2, yheight = 1.0, tmin = 3e4, tmax = 12e4, amin = 75, amax = 105, restore_neutron = 1)

## Input parameters

Parameters in boldface are required; the others are optional.
