THelix has two different constructors.

If a particle with charge q passes through a point (x,y,z) with momentum (px,py,pz) with magnetic field B along an axis (nx,ny,nz), this helix can be constructed like:

THelix p(x,y,z, px,py,pz, q*B, nx,ny,nz);

(nx,ny,nz) defaults to (0,0,1).

THelix

THelix has two different constructors.

Definition THelix.h:23

y

Double_t y[n]

Definition legend1.C:17

x

Double_t x[n]

Definition legend1.C:17

A helix in its own frame can be defined with a pivotal point (x0,y0,z0), the velocity at that point (vx0,vy0,vz0), and an angular frequency w. Combining vx0 and vy0 to a transverse velocity vt0 one can parametrize the helix as:

x(t) = x0 - vt0 / w * sin(-w * t + phi0)
y(t) = y0 + vt0 / w * cos(-w * t + phi0)
z(t) = z0 + vz0 * t

The second constructor has 6 parameters,

Example:

THelix pl1(xyz, v, w, range, rtype, axis);

v

@ v

Definition rootcling_impl.cxx:3687

where:

xyz : array of initial position
v : array of initial velocity
w : angular frequency
range: helix range
rtype: kHelixZ specifies allowed drawing range in helix Z direction, i.e., along B field. kLabZ specifies drawing range in lab frame. kHelixX, kHelixY, kLabX, kLabY, kUnchanged ... etc can also be specified
axis : helix axis

Example constructing a helix with several default values and drawing it:

{
   TCanvas* helix_example_c1 = new TCanvas("helix_example_c1");
   TView *view = TView::CreateView(1);
   view->SetRange(-1,-1,-1,1,1,1);
   THelix *helix = new THelix(0., 0., 0., 1., 0., 0.3, 10.);
   helix->Draw();
}

This initializes a helix with its axis in Z direction (rtype=kHelixZ).
