24 // This class contains the procedures simulation ADC signal for the
25 // Forward Multiplicity detector : Hits->Digits
26 //
27 // Digits consists of
28 // - Detector #
29 // - Ring ID
30 // - Sector #
31 // - Strip #
32 // - ADC count in this channel
33 //
34 // As the Digits and SDigits have so much in common, the classes
35 // AliFMDHitDigitizer and AliFMDSDigitizer are implemented via a base
36 // class AliFMDBaseDigitizer.

47 // +-----------------+ +------------------+
48 //
49 // These classes has several paramters:
50 //
51 // fPedestal
52 // fPedestalWidth
53 // (Only AliFMDHitDigitizer)
54 // Mean and width of the pedestal. The pedestal is simulated
55 // by a Guassian, but derived classes my override MakePedestal
56 // to simulate it differently (or pick it up from a database).
57 //
58 // fVA1MipRange
59 // The dymamic MIP range of the VA1_ALICE pre-amplifier chip
60 //
61 // fAltroChannelSize
62 // The largest number plus one that can be stored in one
63 // channel in one time step in the ALTRO ADC chip.
64 //
65 // fSampleRate
66 // How many times the ALTRO ADC chip samples the VA1_ALICE
67 // pre-amplifier signal. The VA1_ALICE chip is read-out at
68 // 10MHz, while it's possible to drive the ALTRO chip at
69 // 25MHz. That means, that the ALTRO chip can have time to
70 // sample each VA1_ALICE signal up to 2 times. Although it's
71 // not certain this feature will be used in the production,
72 // we'd like have the option, and so it should be reflected in
73 // the code.
74 //
75 // These parameters are fetched from OCDB via the mananger AliFMDParameters.
76 //
77 // The shaping function of the VA1_ALICE is generally given by
78 //
79 // f(x) = A(1 - exp(-Bx))
80 //
81 // where A is the total charge collected in the pre-amp., and B is a
82 // paramter that depends on the shaping time of the VA1_ALICE circut.
83 //
84 // When simulating the shaping function of the VA1_ALICe
85 // pre-amp. chip, we have to take into account, that the shaping
86 // function depends on the previous value of read from the pre-amp.
87 //
88 // That results in the following algorithm:
89 //
90 // last = 0;
91 // FOR charge IN pre-amp. charge train DO
92 // IF last < charge THEN
93 // f(t) = (charge - last) * (1 - exp(-B * t)) + last
94 // ELSE
95 // f(t) = (last - charge) * exp(-B * t) + charge)
96 // ENDIF
97 // FOR i IN # samples DO
98 // adc_i = f(i / (# samples))
99 // DONE
100 // last = charge
101 // DONE
102 //
103 // Here,
104 //
105 // pre-amp. charge train
106 // is a series of 128 charges read from the VA1_ALICE chip
107 //
108 // # samples
109 // is the number of times the ALTRO ADC samples each of the 128
110 // charges from the pre-amp.
111 //
112 // Where Q is the total charge collected by the VA1_ALICE
113 // pre-amplifier. Q is then given by
114 //
115 // E S
116 // Q = - -
117 // e R
118 //
119 // where E is the total energy deposited in a silicon strip, R is the
120 // dynamic range of the VA1_ALICE pre-amp (fVA1MipRange), e is the
121 // energy deposited by a single MIP, and S ALTRO channel size in each
122 // time step (fAltroChannelSize).
123 //
124 // The energy deposited per MIP is given by
125 //
126 // e = M * rho * w
127 //
128 // where M is the universal number 1.664, rho is the density of
129 // silicon, and w is the depth of the silicon sensor.
130 //
131 // The final ADC count is given by
132 //
133 // C' = C + P
134 //
135 // where P is the (randomized) pedestal (see MakePedestal)
136 //
137 // This class uses the class template AliFMDMap<Type> to make an
138 // internal cache of the energy deposted of the hits. The class
139 // template is instantasized as
140 //
141 // typedef AliFMDMap<std::pair<Float_t, UShort_t> > AliFMDEdepMap;
142 //
143 // The first member of the values is the summed energy deposition in a
144 // given strip, while the second member of the values is the number of
145 // hits in a given strip. Using the second member, it's possible to
146 // do some checks on just how many times a strip got hit, and what
147 // kind of error we get in our reconstructed hits. Note, that this
148 // information is currently not written to the digits tree. I think a
149 // QA (Quality Assurance) digit tree is better suited for that task.
150 // However, the information is there to be used in the future.
