the collecting electrode) is siLriultaneouslj meqsured. The accuracy

ABSTRACT According,.t6 ihw data obtained from publications this coGfficient in pro-
bably'large. Theauthors,detarmined this conversion coefficient by means of
the method of 4-y coincidences. An.enrichod U434 source was used. The a-
1~articlem were-recordtd by me" of a momentum ionization chamber and the
y-quanta by means of a scintillation counter with an N&J(Tl)-cryst&l. The
y-xpectrum was recorded in coincidence with the a-particles which lead to
the basic level and to the first-eicited level,of the Th 230. This racU ation
originates entirely from the inner c6iiversion on the L-shells of the Th230.
The coefficient of conversion was determined from the ratio of the numb6r ?j

ABSTRACT: It ip known from the Nyquist theory that the noise pro-
duced.by the grid current can be expressed by:

where *r - RCt Ic is the grid current; R is the grid leak
of the tube and 0 is its input capacitance; function F(w)
in Eq (3) is formed by the product of the transfer functions
of an integrating and a differentiating network; the time

the grid current noise can be expressed by Eq (4). where
q X~T/T . If the tube contains a resistor- R at its input,
the noisedue to this can be expressed by Eq (6). Provided
the same function F(w) is used, the integration of Eq (6)
results in 1,
'q (7). The maximum value of the thermal noise,
expressed by Eq (7) occurs when the resistance is given by
Eq (8); this value Is given by Eq (9). On the other hand,
the maximum value of the noise produced by the grid current
is given by Eq (5). Consequently, the grid current can be
expressed in terms of a ratio of the maximum grid current
noise to the thermal noise and this is expressed by Eq (10).
This equation can be used for determining the value of IC .
By comparing Eqs (3) and (6), it is found that the relation-
ship between the grid current noise and the thermal noise is
expressed by Eq (15). This can also be used for determining
IC ; for example, if a value of R is determined such that
the current noise is equal to the thermal noise, the grid
current is given by Eq (16); here$ RO is the value of R
necessary to secure the equality of the two noises. The above

ABSTRACT: A calculation 13 made of the optimum bandwidth of an
amplifter with two differentiating circuits. It is shown
that the introduction of the second.differentiating
circuit completely avoids the influence of microphonic
effects and low frequency noise without deteriorating the
signal-to-noi3e ratio, The resolving power of an
ionization alpha-spectrometer is determined basically by
the noise In the first valve. When the leakage
resistance of the first valve Is high enough thermal
noise may be :.,ieglected and only the contributions (if
anodeand grid current taken intn account. Usually the
maximum signal-to-noise ratio is guaranteed by correct
choice of amplifier bandwidth.and,this usually means
Card 1/4 Inserting a differentiating and an integrating cirouit.
This case has already been considered by Elmore In Ref 1.

The Choice of Optimum.Pa.33-band in an Amplifier Working with an
Ionization Champer
:This scheme ha:j a number of drawbacksi in particular the
location of the differentiating circuit is difficult,
since it is preferable to place it before the amplifier
in order to avoid overloading on microphony, but also
convenient to place the circuit within the middle of the
amplifier when A.C. heaters are used. In the analysis
-for brevity an arrangement of one differentiator followed
by one integrator is described as [1,11; the cases J1121
(2)2j are also considered. The spectral densities of the
grid and anode currents are given by Eqs (1) and (2).
For the three circuit combinations described above7
expressions for the minimum value of noise are given by
Eqs (8), (12) and (17). In the many curves which are
presented two parameters are used; p which is the
ratio of the time constants of the integrator and the
differentiator circuits, and a which is defined in
Eq (5). In calculating signal-to-noise ratio it is
assumed that a rectangular voltage pulse is delivered
Card 2/4 from the ionization chamber. Signal-to-noise ratio is
denoted by Q ., In Fig 1 the signal-to-noise ratio is

dotted 1-Ines. Figs 3~ 4 and 5 show for the three
circuit arrangements Pespectively the variation of
signal-to-noise ratto wiU, p fcr various pulse
diarations. Figs 6, 7 and 8 ai-e the corresponding
figures with p and a as parameters. Ionization
chambers suffer from microphony at frequencies up to
100 cls. By using two differentiating circuits the
contribution to the mir;rophony may be redu(,ed with
respect to that due to valve raise by a factor of
approximately 100 at a frequenoy of 100 c1s; at lower
frequencies this reduction is even more significant.
It has so far been assumed that the voltage pulses are
truly rectangalar;. in practice they have sloping fronts
and if these slopes are linear it Is possible to
calculate easily the loss in amplitude as a function of
the differentiating and integrating circuits. This
loss is shown plotted in Figs 9 and 10 respectively for
single and double cirouits. Table 1 summarizes the

circuits the relationship between amplitude loss and
rise time is 4uadratic. In Table 2 experimental and
calculated results are compared for various values of
differentiator and integrator time constant; this table
applies to the case of jl,2j .The authors thank

ABSTRACT: The purpose of the piper in to verify the influence of Hamsauer-
Townsend effect on the mobility of electrons In upectroocapic-
ally pure argon. The study is experim(mital in naturc. The
drift of electrons is measured as a function of E/p, wh,:re E
is intensity of the electric field and p in barometric pressure-
of argon in the experimental chamber. The experiments were
carried out for values 'of E/p, between 0.001and 1.5. At small
values of E/p a maximum was observed similar to that obtained
by other investigators. This maximum could be explained at; thc-
result of the Rarisauer-Townsend effect, or it might havk:! b(,en
caused by the excitation ofniolecular levels owing to the pre:;(-n,:e
of impurities in argon. For this reason industrial argon of ~9.6%
