Slapper detonator

<h2 id="advantages">Advantages</h2>

<p>Advantages over explosive-bridgewire detonators include:
</p>
<ul><li>The foil does not come in contact with the explosive, which reduces the risk of corrosion of the foil or chemical reactions between the foil and explosive producing unstable compounds, and secondarily further reduces the risk of accidental electrical ignition of the explosive.</li>
<li>The energy to fire the detonator is quite low</li>
<li>The slapper pellet impacting an area of explosives rather than a single point as in an EBW is more reliable and efficient at initiating detonation.</li>
<li>The explosive can be pressed to higher density</li>
<li>Very insensitive explosives can be initiated directly.</li></ul>
<p>In a variant called laser detonator the vaporization can be caused by a high-power <a href="/facts/Laser/jk6PTvvT">laser</a> pulse delivered over-the-air or coupled by an <a href="/facts/Optical_fiber/5ruuIFbj">optical fiber</a>; this is reportedly used as a safety detonator in some <a href="/facts/Mining/g6uDIFab">mining</a> operations and <a href="/facts/Quarry/s6fhrNhe">quarries</a>. Typically a 1-watt <a href="/facts/List_of_laser_types/wGEmLDVD">solid-state laser</a> is used.
