If the requested instruement exists, check if it contains the requested channelnumber by checking how many channels it has. If it contains the channel return a pointer to it. If the channel number is bigger than the number of channels in the instrument, throw an invalid_argument exception.

double cass::ACQIRIS::findXForGivenY	(	const double *	x,

	)

Achims Numerical Approximation.

this function should find x value corrosponding to a given y value in a newton polynomial. It does it the following way:

create a lower and upper boundary point
create an interating x-value and initialize it with the Start value
evaluate the y-value at the x-value
if the y value is bigger than the requested value the start point is defines the new upper or lower boundary depending on the slope.
the new x-point is defined by the arithmetic mean between the tow boundary points.
do points 3-5 until the new x-value does not differ more than 0.005 from the old one.

Parameters

[in]	x	two points describing upper and lower boundaries
[in]	coeff	the newton polynomial coefficents
[in]	Y	the requested y-values to find the x-value for
[in]	Start	the x-value we start the search with

		double	y_mm,

		double &	px_au,

	)

calculate Momentum in Detektor Plane

calculates the momentum of the particle in the detector plane. This is for the case that a magnetic field is present in the spectrometer. Usually this is there because one wants to collect all electrons in the spectrometer.

First calculate the total momentum in the detector plane. Then we have to find out where the initial direction of emmision this means we need to find the angle between the x-axis and the emission angle phi.The angle depends whether the cyclotron motion is ccw or cw, meaning the B-Field is pointing into the detektor-plane or out of the detector plane respectivly.

Parameters

[in]	x_mm	the x position of the hit in mm
[in]	y_mm	the y position of the hit in mm
[in]	tof_ns	the time of flight of the hit in ns
[in]	particle	the particle properties

calculate the momentum in the detector plane

calculate the momentum in the detector plane in case when there is no magnetic field present. This is simply done by calulating the velocity of the particle perpendicular to the time of flight axis when it hits the detector. This is determined by the time if flew and the position it hit the detector.

Returns: the momentum of the particle along the axis

Parameters

return range of possible anode wire signal candidates

For a given Mcp time there are only a few signal on the wire ends that can come with the Mcp Signal. This function will find the indexs of the list of signals which might come together with the mcp signal. This is because we know two things (ie. for the x-layer): $|x_1-x_2|<rTime_x$ and $x_1+x_2-2*mcp = ts_x$ with this knowledge we can calculate the boundries for the anode given the Timesum and the Runtime.

Returns: pair of iterator that define the range

Parameters

sigs	the vector of signals of the anode wire end
mcp	the Mcp Signal for which to find the right wire end signals
ts	The timesum of the Anode
rTime	The runtime of a Signal over the whole wire of the anode

Momentum along time of flight.

this will use a direct direct calculation since there is only one spectrometer region.

calculates the acceleration from the E-field in the region, charge and mass of the particle. The result will be in $\frac{mm^2}{ns}$ . With this one can calculate the velocity of the particle after it has reached the detector in $\frac{mm}{ns}$ . After converting $\frac{mm}{ns}$ to atomic units one simply has to multiply the velocity with the mass in atomic units to get momentum in atomic units.

Returns: the momentum along the time of flight axis in atomic units

Parameters

tof_ns	the time of flight of the hit in ns
mass_au	the mass of the particle in atomic units
charge_au	the charge of the particle in atomic units
sr	the spectrometer region through which the particle flys.

Momentum along time of flight.

find momentum iterativly. There is no analytical solution for when there are more than two spectrometer regions through which the particle is flying.

We have measured the time of flight of the particle, what we need to find out is to which initial momentum does this time of flight fit. Since we have a function that will calculate the time of flight for a given intial velocity, we can now use this function and vary the intial velocity so long until the measured time of flight is the same as the calculated time of flight for a chosen velocity.
Our initail guess for the velocity is the velocity the particle would have, when there is only one spectrometer region. So first calculate the velocity for when only the first region of the spectrometer would exist. Then calculate the tof for this velocity and find the next step of the iteration using Newtons Approximation. This means that we calculate the slope of the function at the current position. The next iteration is where the linear function with the slope crosses the right fx0. Do this until the time of flight is close to the one we measured. Then calculate the momentum of particle whos velocity gave the right time of flight.

Returns: the momentum along the time of flight axis in atomic units only the tof_ns parameter is non negative. When it is negative return a high number (1e15)

Parameters

tof_ns	the time of flight of the hit in ns
mass_au	the mass of the particle in atomic units
charge_au	the charge of the particle in atomic units
spectrometer	the spectrometer through which the particle is flying

load layer from file

load the requested layer from .ini file and checks whether it is valid. If it is not valid an invalid_argument exception is thrown

Returns: key containing the layer name

Parameters

s	CASSSettings object to read the info from
detector	the name of the detector that contains the layer
layerKey	key how the layer value is called in the .ini file
ppNbr	the processor number of the processor calling this function
key	the key of the processor calling this function

load particle for a specific detector

after loading check whether it is a delayline detector, if not throw invalid_argument exception.

Returns: key containing detector name

Parameters

s	CASSSettings object to read the info from
detector	the name of the detector that contains the layer
